General DescriptionThe MAX6335/MAX6336/MAX6337 microprocessor (µP)supervisory circuits monitor the power supplies in 1.8V to 3.3V µP and digital systems. They increase circuit reli-ability and reduce cost by eliminating external compo-nents and adjustments. They also feature a debounced manual-reset input.These devices perform a single function: they assert a reset signal whenever the V CC supply voltage declines below a preset threshold or whenever manual reset is asserted. Reset remains asserted for a preset timeout period after V CC has risen above the reset threshold or after manual reset is deasserted. The only difference among the three devices is their output. The MAX6336(push/pull) and MAX6337 (open-drain) have an active-low RESET output, while the MAX6335 (push/pull) has an active-high RESET output. The MAX6335/MAX6336are guaranteed to be in the correct state for V CC down to 0.7V. The MAX6337 is guaranteed to be in the cor-rect state for V CC down to 1.0V.The reset comparator in these ICs is designed to ignore fast transients on V CC . Reset thresholds are factory-trimmable between 1.6V and 2.5V, in approximately 100mV increments. There are 15 standard versions available (2500 piece minimum-order quantity); contact the factory for availability of nonstandard versions (10,000 piece minimum-order quantity). For space-criti-cal applications, the MAX6335/MAX6336/MAX6337come packaged in a 4-pin SOT143.ApplicationsPentium II™ Computers Computers ControllersIntelligent InstrumentsCritical µP/µC Power Monitoring Portable/Battery-Powered Equipment AutomotiveFeatures♦Ultra-Low 0.7V Operating Supply Voltage♦Low 3.3µA Supply Current♦Precision Monitoring of 1.8V and 2.5V Power-Supply Voltages ♦Reset Thresholds Available from 1.6V to 2.5V,in Approximately 100mV Increments ♦Debounced Manual Reset ♦Fully Specified over Temperature♦Three Power-On Reset Pulse Widths Available (1ms min, 20ms min, 100ms min)♦Low Cost♦Three Available Output Structures: Push/Pull RESET , Push/Pull RESET, Open-Drain RESET ♦Guaranteed RESET/RESET Valid to V CC = 0.7V (MAX6335/MAX6336)♦Power-Supply Transient Immunity ♦No External Components ♦4-Pin SOT143 Package♦Pin Compatible with MAX811/MAX812 and MAX6314/MAX6315MAX6335/MAX6336/MAX63374-Pin, Ultra-Low-Voltage, Low-Power µP Reset Circuits with Manual Reset________________________________________________________________Maxim Integrated Products 119-1412; Rev 2; 12/05Ordering Information* These devices are available in factory-set V CC reset thresh-olds from 1.6V to 2.5V, in approximately 0.1V increments.Choose the desired reset threshold suffix from Table 1 and insert it in the blanks following “US” in the part number.Factory-programmed reset timeout periods are also available.Insert the number corresponding to the desired nominal reset timeout period (1 = 1ms min, 2 = 20ms min, 3 = 100ms min) in the blank following “D” in the part number.

A logic low on MR asserts reset. Reset remains asserted while MR is low,and for the reset active timeout period after MR returns high. MR has an internal 20k Ωpull-up resistor, so it can be left unconnected if not used. Connect a normally open momentary switch from MR to G ND to create a manual-reset function; external debounce circuitry is not required.Interfacing to µPs with Bidirectional Reset PinsSince the RESET output on the MAX6337 is open-drain,this device interfaces easily with µPs that have bidirec-tional reset pins, such as the Motorola 68HC11.Connecting the µP supervisor’s RESET output directly to the microcontroller’s (µC’s) RESET pin with a single pull-up resistor allows either device to assert reset (Figure 1).Negative-Going V CC TransientsIn addition to issuing a reset to the µP during power-up,power-down, and brownout conditions, these devices are relatively immune to short-duration, negative-going V CC transients (glitches). The Typical Operating Characteristics show the Maximum Transient Duration vs. Reset Comparator Overdrive graph. The graph shows the maximum pulse width that a negative-going V CC transient may typically have without issuing a resetsignal. As the amplitude of the transient increases, the maximum allowable pulse width decreases.Ensuring a Valid Reset Outputdown to V CC = 0When V CC falls below 1V and approaches the minimum operating voltage of 0.7V, push/pull-structured reset sinking (or sourcing) capabilities decrease drastically.High-impedance CMOS-logic inputs connected to the RESET pin can drift to indeterminate voltages. This does not present a problem in most cases, since most µPs and circuitry do not operate at V CC below 1V. For the MAX6336, where RESET must be valid down to 0,adding a pull-down resistor between RESET and GND removes stray leakage currents, holding RESET lowFigure 1. Interfacing to µPs with Bidirectional Reset Pins4-Pin, Ultra-Low-Voltage, Low-Power µP Reset Circuits with Manual Reset_______________________________________________________________________________________5MAX6335/MAX6336/MAX6337*Factory-trimmed reset thresholds are available in approximately 100mV increments, with a ±1.8% room-temperature variance.Table 1. Factory-Trimmed Reset Thresholds*Figure 2. Ensuring Reset Valid down to V CC = 0(Figure 2a). The pull-down resistor value is not critical;100k Ωis large enough not to load RESET , and small enough to pull it low. For the MAX6335, where RESET must be valid to V CC = 0, a 100k Ωpull-up resistor between RESET and V CC will hold RESET high when V CC falls below 0.7V (Figure 2b).Since the MAX6337 has an open-drain, active-low out-put, it typically uses a pull-up resistor. With this device,RESET will most likely not maintain an active condition,but will drift to a non-active level due to the pull-up resistor and the reduced sinking capability of the open-drain device. Therefore, this device is not recommend-ed for applications where the RESET pin is required to be valid down to V CC = 0.M A X 6335/M A X 6336/M A X 63374-Pin, Ultra-Low-Voltage, Low-Power µP Reset Circuits with Manual Reset 6_______________________________________________________________________________________PARTOUTPUT STAGE NOMINAL V TH (V)MINIMUM RESET TIMEOUT (ms)SOT TOP MARKMAX6335US23D3-T Push/Pull RESET 2.30100KABQ MAX6335US22D3-T Push/Pull RESET 2.20100KAAR MAX6335US20D3-T Push/Pull RESET 2.00100KABP MAX6335US18D3-T Push/Pull RESET 1.80100KAAQ MAX6335US16D3-T Push/Pull RESET 1.60100KAAP MAX6336US23D3-T Push/PullRESET 2.30100KAAW MAX6336US22D3-T Push/Pull RESET 2.20100KAAV MAX6336US20D3-T Push/Pull RESET 2.00100KAAU MAX6336US18D3-T Push/Pull RESET 1.80100KAAT MAX6336US16D3-T Push/Pull RESET 1.60100KAAS MAX6337US23D3-T Open-Drain RESET 2.30100KABS MAX6337US22D3-T Open-Drain RESET 2.20100KAAZ MAX6337US20D3-T Open-Drain RESET 2.00100KABRMAX6337US18D3-T Open-Drain RESET 1.80100KAAY MAX6337US16D3-TOpen-Drain RESET1.60100KAAXSelector Guide (standard versions *)Pin ConfigurationTypical Operating Circuit* Sample stock is generally held on all standard versions.4-Pin, Ultra-Low-Voltage, Low-Power µP Reset Circuits with Manual ResetTRANSISTOR COUNT:505Chip InformationPackage Information(The package drawing(s) in this data sheet may not reflect the most current specifications.

The SSR differs in that it has no moving mechanical parts within it. It is essentially an electronic device that relies on the electrical, magnetic and optical properties of semiconductors, and electrical components to achieve its isolation and relay switching function.Principle of Operation: Solid State Relays are similar to electromechanical relays, in that both use a control circuit and a separate circuit for switching the load. When voltage is applied to the input of the SSR, the relay is energized by a light emitting diode. The light from the diode is beamed into a light sensitive semiconductor which, in the case of zero voltage crossover relays, conditions the control circuit to turn on the output solid state switch at the next zero voltage crossover. In the case of nonzero voltage crossover relays, the output solid state switch is turned on at the precise voltage occurring at the time. Removal of the input power disables the control circuit and the solid state switch is turned off when the load current passes through the zero point of its cycle.Applications: Since its introduction the SSR, as a technology, has gained acceptance in many areas, which had previously been the sole domain of the EMR or the Contactor. The major growth areas have come from Industrial Process Control applications; particularly heat/cool temperature control, motors, lamps, solenoids, valves, and transformers. The list of applications for the SSR is almost limitless.The following are typical examples of SSR applications: industrial automation, electronic appliances, industrial appliances, packaging machines, tooling machines, manufacturing equipment, food equipment, security systems, industrial lighting, fire and security systems, dispensing machines, production equipment, on-board power control, traffic control, instrumentation systems, vending machines, test systems, office machines, medical equipment, display lighting, elevator control, metrology equipment, and entertainment lighting.Advantages: When used correctly in the intended application, the SSR provides many of the characteristics that are often difficult to find in the EMR; a high degree of reliability, long service life, significantly reduced electromagnetic interference, fast response and high vibration resistance are significant benefits of the SSR. The SSR has no moving parts to wear out or arcing contacts to deteriorate, which are often the primary cause of failure with an EMR.Thermal Considerations: One of the major considerations when using a SSR is properly managing the heat that is generated when switching currents higher than about 5 amps. In this scenario one must mount the base plate of the SSR onto a good heat conductor, typically aluminum; along with utilizing a good thermal transfer medium such as thermal grease or heat transfer pad. Using this technique, the SSR case to heat sink thermal resistance is reduced to a negligible value of 0.1 ˚C/W.INDUSTRIALALARM ELECTRONIC PACKING MEDICAL INDUSTRIAL TOOLING • Long life (reliability) > 109 operations • Zero voltage turn on, low EMI / RFI • Shock and Vibration resistant• Random turn-on, proportional control • No contact bounce• Arc-less switching • No acoustical noise• Microprocessor compatible • Fast response • No moving partsSolid State Relays – Application Data4/2S E C T I O N 4Magnecraft Solution Guide 105ALegacyOptional Heat Sink(SSR-HS-1)Section 3 p.20Optional Thermal Pad(SSR-TP-1)Section 3 p.21We at Magnecraft strive to be your one-stop-shop for all of your solid state relay needs.

The MAX6305/MAX6308/MAX6311 have two adjustable undervoltage reset inputs (RST IN1 and RST IN2). The MAX6306/MAX6307/MAX6309/MAX6310/MAX6312/MAX6313 mon-itor V CC through an internal, factory-trimmed voltage divider. The MAX6306/MAX6309/MAX6312 have, in addition, an adjustable undervoltage reset input and a manual-reset input. The internal voltage divider sets the reset threshold as specified in the device part number (Table 1). The MAX6307/MAX6310/ MAX6313 feature an adjustable undervoltage reset input (RST IN) and an adjustable overvoltage reset input (OVRST IN) in addition to the factory-trimmed reset threshold on the V CC moni-tor. Program the adjustable reset inputs with an external resistor divider (see Adjustable Reset Inputs section).Reset OutputsA µP’s reset input starts the µP in a known state. These µP supervisory circuits assert reset to prevent code-execution errors during power-up, power-down, or brownout conditions.RESET (MAX6305–MAX6310) and RESET (MAX6311/MAX6312/MAX6313) are guaranteed to be asserted at a valid logic level for V CC > 1V (see Electrical Characteristics ). Once all monitored voltages exceed their programmed reset thresholds, an internal timer keeps reset asserted for the reset timeout period (t RP );after this interval, reset deasserts.If a brownout condition occurs (any or all monitored volt-ages dip outside their programmed reset threshold),reset asserts (RESET goes high; RESET goes low). Any time any of the monitored voltages dip below their reset threshold, the internal timer resets to zero and reset asserts. The internal timer starts when all of the moni-tored voltages return above their reset thresholds, and reset remains asserted for a reset timeout period. The MAX6305/MAX6306/MAX6307 feature an active-low,MAX6305–MAX63135-Pin, Multiple-Input, Programmable Reset ICs_______________________________________________________________________________________5______________________________________________________________Pin DescriptionM A X 6305–M A X 6313open-drain, N-channel output. The MAX6308/MAX6309/MAX6310 feature an active-low, complementary output structure that both sinks and sources current, and the MAX6311/MAX6312/MAX6313 have an active-high com-plementary reset output.The MAX6305/MAX6308/MAX6311 switch from under-voltage lockout operation to normal operation between 1.5V < V CC < 2.5V. Below 1.5V, V CC undervoltage-lockout mode asserts RESET . Above 2.5V, V CC normal-operation mode asserts reset if RST IN_ falls below the RST IN_ threshold.Manual-Reset Input(MAX6306/MAX6309/MAX6312)Many µP-based products require manual-reset capability,allowing an operator or external logic circuitry to initiate a reset. A logic low on MR asserts reset. Reset remains asserted while MR is low, and for a reset active timeout period (t RP ) after MR returns high. This input has an inter-nal 63.5k Ωpull-up resistor, so it can be left open if it is not used. MR can be driven with TTL-logic levels in 5V sys-tems, with CMOS-logic levels in 3V systems, or with open-drain/collector output devices. Connect a normally open momentary switch from MR to GND to create a manual-reset function; external debounce circuitry is not required.If MR is driven from long cables or if the device is used in a noisy environment, connecting a 0.1µF capacitor from MR to ground provides additional noise immunity.The MR pin has internal ESD-protection circuitry that may be forward biased under certain conditions, drawing excessive current. For example, assume the circuitry driv-ing MR uses a +5V supply other than V CC . If V CC drops or browns out lower than +4.7V, MR ’s absolute maximum rat-ing is violated (-0.3V to (V CC + 0.3V)), and undesirable current flows through the ESD structure from MR to V CC .To avoid this, it is recommended that the supply for the MR pin be the same as the supply monitored by V CC . In this way, the voltage at MR will not exceed V CC .Adjustable Reset InputsThe MAX6305–MAX6313 each have one or more reset inputs (RST IN_ /OVRST IN). These inputs are com-pared to the internal reference voltage (Figure 1).Connect a resistor voltage divider to RST IN_ such that V RST IN_falls below V RSTH (1.23V) when the monitored voltage (V IN ) falls below the desired reset threshold (V TH ) (Figure 2). Calculate the desired reset voltage with the following formula:R1 + R2V TH = ________x V RSTHR25-Pin, Multiple-Input, Programmable Reset ICs 6_______________________________________________________________________________________Figure 1. Functional DiagramMAX6305–MAX63135-Pin, Multiple-Input, Programmable Reset ICs_______________________________________________________________________________________7The ±25nA max input leakage current allows resistors on the order of megohms. Choose the pull-up resistor in the divider to minimize the error due to the input leakage cur-rent. The error term in the calculated threshold is simply:±25nA x R1If you choose R1 to be 1M Ω, the resulting error is ±25 x 10-9x 1 x 106= ±25mV.Like the V CC voltage monitors on the MAX6306/MAX6307/MAX6309/MAX6310/MAX6312/MAX6313, the RST IN_inputs (when used with a voltage divider) are designed to ignore fast voltage transients. Increase the noise immunity by connecting a capacitor on the order of 0.1µF between RST IN and GND (Figure 2). This creates a single-pole lowpass filter with a corner frequency given by:f = (1/2π) / (R1 + R2)(R1 x R2 x C)For example, if R1 = 1M Ωand R2 = 1.6M Ω, adding a 0.1µF capacitor from RST IN_ to ground results in a lowpass corner frequency of f = 2.59Hz. Note that adding capacitance to RST IN slows the circuit’s overall response time.__________Applications InformationInterfacing to µPs with Bidirectional Reset PinsSince the RESET output on the MAX6305/MAX6306/MAX6307 is open drain, these devices interface easily with µPs that have bidirectional reset pins, such as the Motorola 68HC11. Connecting the µP supervisor’s RESET output directly to the microcontroller’s RESET pin with a single pull-up resistor allows either device to assert reset (Figure 3).Negative-Going V CC TransientsIn addition to issuing a reset to the µP during power-up,power-down, and brownout conditions, these devices are relatively immune to short-duration, negative-going V CC transients (glitches).The Typical Operating Characteristics show the Maximum Transient Duration vs. V CC Reset Threshold Overdrive, for which reset pulses are not generated.The graph was produced using negative-going pulses,starting at V TH max, and ending below the pro-grammed reset threshold by the magnitude indicated (reset threshold overdrive). The graph shows the maxi-mum pulse width that a negative-going V CC transient may typically have without causing a reset pulse to be issued. As the amplitude of the transient increases (i.e.,goes farther below the reset threshold), the maximum allowable pulse width decreases.RST IN_/OVRST IN are also immune to negative/positive-going transients (see Typical Operating Characteristics ).A 0.1µF bypass capacitor mounted close to the RST IN_,OVRST IN, and/or the V CC pin provides additional tran-sient immunity.Ensuring a Valid RESET /RESETOutput Down to V CC = 0VWhen V CC falls below 1V, push/pull structured RESET /RESET current sinking (or sourcing) capabilities decrease drastically. High-impedance CMOS-logic inputs connected to RESET can drift to undetermined voltages. This presents no problem in most applica-tions, since most µPs and other circuitry do not operate with V CC below 1V. In those applications where RESET must be valid down to 0V, adding a pull-down resistor between RESET and ground sinks any stray leakageFigure 2. Increasing Noise ImmunityFigure 3. Interfacing to µPs with Bidirectional Reset I/Ocurrents, holding RESET low (Figure 4). The pull-down resistor’s value is not critical; 100k Ωis large enough not to load RESET and small enough to pull RESET to ground. For applications where RESET must be valid to V CC , a 100k Ωpull-up resistor between RESET and V CC will hold RESET high when V CC falls below 1V (Figure 5).Since the MAX6305/MAX6306/MAX6307 have open-drain, active-low outputs, they typically use a pull-up resistor. With these devices and under these conditions (V CC < 1V), RESET will most likely not maintain an active condition, but will drift toward a nonactive level due to the pull-up resistor and the RESET output’s reduction in sinking capability. These devices are not recommended for applications that require a valid RESET output below 1V.* Factory-trimmed reset thresholds are available in approximately 100mV increments with a ±1.5% room-temperature variance.M A X 6305–M A X 63135-Pin, Multiple-Input, Programmable Reset ICs 8_______________________________________________________________________________________Figure 4.

General DescriptionThe MAX220–MAX249 family of line drivers/receivers is intended for all EIA/TIA-232E and V.28/V.24 communica-tions interfaces, particularly applications where ±12V is not available.These parts are especially useful in battery-powered sys-tems, since their low-power shutdown mode reduces power dissipation to less than 5µW.

MAX247/MAX248/MAX249 Control Pin ConfigurationsM A X 220–M A X 249_______________Detailed DescriptionThe MAX220–MAX249 contain four sections: dual charge-pump DC-DC voltage converters, RS-232 dri-vers, RS-232 receivers, and receiver and transmitter enable control inputs.Dual Charge-Pump Voltage ConverterThe MAX220–MAX249 have two internal charge-pumps that convert +5V to ±10V (unloaded) for RS-232 driver operation. The first converter uses capacitor C1 to dou-ble the +5V input to +10V on C3 at the V+ output. The second converter uses capacitor C2 to invert +10V to -10V on C4 at the V- output.A small amount of power may be drawn from the +10V (V+) and -10V (V-) outputs to power external circuitry (see the Typical Operating Characteristics section),except on the MAX225 and MAX245–MAX247, where these pins are not available. V+ and V- are not regulated,so the output voltage drops with increasing load current.Do not load V+ and V- to a point that violates the mini-mum ±5V EIA/TIA-232E driver output voltage when sourcing current from V+ and V- to external circuitry. When using the shutdown feature in the MAX222,MAX225, MAX230, MAX235, MAX236, MAX240,MAX241, and MAX245–MAX249, avoid using V+ and V-to power external circuitry. When these parts are shut down, V- falls to 0V, and V+ falls to +5V. For applica-tions where a +10V external supply is applied to the V+pin (instead of using the internal charge pump to gen-erate +10V), the C1 capacitor must not be installed and the SHDN pin must be tied to V CC . This is because V+is internally connected to V CC in shutdown mode.RS-232 DriversThe typical driver output voltage swing is ±8V when loaded with a nominal 5k ΩRS-232 receiver and V CC =+5V. Output swing is guaranteed to meet the EIA/TIA-232E and V.28 specification, which calls for ±5V mini-mum driver output levels under worst-case conditions.These include a minimum 3k Ωload, V CC = +4.5V, and maximum operating temperature. Unloaded driver out-put voltage ranges from (V+ -1.3V) to (V- +0.5V). Input thresholds are both TTL and CMOS compatible.The inputs of unused drivers can be left unconnected since 400k Ωinput pull-up resistors to V CC are built in (except for the MAX220). The pull-up resistors force the outputs of unused drivers low because all drivers invert.The internal input pull-up resistors typically source 12µA,except in shutdown mode where the pull-ups are dis-abled. Driver outputs turn off and enter a high-imped-ance state—where leakage current is typically microamperes (maximum 25µA)—when in shutdownmode, in three-state mode, or when device power is removed. Outputs can be driven to ±15V. The power-supply current typically drops to 8µA in shutdown mode.The MAX220 does not have pull-up resistors to force the ouputs of the unused drivers low. Connect unused inputs to GND or V CC .The MAX239 has a receiver three-state control line, and the MAX223, MAX225, MAX235, MAX236, MAX240,and MAX241 have both a receiver three-state control line and a low-power shutdown control. Table 2 shows the effects of the shutdown control and receiver three-state control on the receiver outputs.The receiver TTL/CMOS outputs are in a high-imped-ance, three-state mode whenever the three-state enable line is high (for the MAX225/MAX235/MAX236/MAX239–MAX241), and are also high-impedance whenever the shutdown control line is high.When in low-power shutdown mode, the driver outputs are turned off and their leakage current is less than 1µA with the driver output pulled to ground. The driver output leakage remains less than 1µA, even if the transmitter output is backdriven between 0V and (V CC + 6V). Below -0.5V, the transmitter is diode clamped to ground with 1k Ωseries impedance. The transmitter is also zener clamped to approximately V CC + 6V, with a series impedance of 1k Ω.The driver output slew rate is limited to less than 30V/µs as required by the EIA/TIA-232E and V.28 specifica-tions. Typical slew rates are 24V/µs unloaded and 10V/µs loaded with 3Ωand 2500pF.RS-232 ReceiversEIA/TIA-232E and V.28 specifications define a voltage level greater than 3V as a logic 0, so all receivers invert.Input thresholds are set at 0.8V and 2.4V, so receivers respond to TTL level inputs as well as EIA/TIA-232E and V.28 levels.The receiver inputs withstand an input overvoltage up to ±25V and provide input terminating resistors withDrivers/Receivers 14Table 2. Three-State Control of ReceiversMAX220–MAX249Drivers/Receivers______________________________________________________________________________________15nominal 5k Ωvalues. The receivers implement Type 1interpretation of the fault conditions of V.28 and EIA/TIA-232E.The receiver input hysteresis is typically 0.5V with a guaranteed minimum of 0.2V. This produces clear out-put transitions with slow-moving input signals, even with moderate amounts of noise and ringing. The receiver propagation delay is typically 600ns and is independent of input swing direction.Low-Power Receive ModeThe low-power receive-mode feature of the MAX223,MAX242, and MAX245–MAX249 puts the IC into shut-down mode but still allows it to receive information. This is important for applications where systems are periodi-cally awakened to look for activity. Using low-power receive mode, the system can still receive a signal that will activate it on command and prepare it for communi-cation at faster data rates. This operation conserves system power.Negative Threshold—MAX243The MAX243 is pin compatible with the MAX232A, differ-ing only in that RS-232 cable fault protection is removed on one of the two receiver inputs. This means that control lines such as CTS and RTS can either be driven or left floating without interrupting communication. Different cables are not needed to interface with different pieces of equipment.The input threshold of the receiver without cable fault protection is -0.8V rather than +1.4V. Its output goes positive only if the input is connected to a control line that is actively driven negative. If not driven, it defaults to the 0 or “OK to send” state. Normally‚ the MAX243’s other receiver (+1.4V threshold) is used for the data line (TD or RD)‚ while the negative threshold receiver is con-nected to the control line (DTR‚ DTS‚ CTS‚ RTS, etc.). Other members of the RS-232 family implement the optional cable fault protection as specified by EIA/TIA-232E specifications. This means a receiver output goes high whenever its input is driven negative‚ left floating‚or shorted to ground. The high output tells the serial communications IC to stop sending data. To avoid this‚the control lines must either be driven or connected with jumpers to an appropriate positive voltage level.Shutdown—MAX222–MAX242On the MAX222‚ MAX235‚ MAX236‚ MAX240‚ and MAX241‚ all receivers are disabled during shutdown.On the MAX223 and MAX242‚ two receivers continue to operate in a reduced power mode when the chip is in shutdown. Under these conditions‚ the propagation delay increases to about 2.5µs for a high-to-low input transition. When in shutdown, the receiver acts as a CMOS inverter with no hysteresis. The MAX223 and MAX242 also have a receiver output enable input (EN for the MAX242 and EN for the MAX223) that allows receiver output control independent of SHDN (SHDN for MAX241). With all other devices‚ SHDN (SH DN for MAX241) also disables the receiver outputs.The MAX225 provides five transmitters and five receivers‚ while the MAX245 provides ten receivers and eight transmitters. Both devices have separate receiver and transmitter-enable controls. The charge pumps turn off and the devices shut down when a logic high is applied to the ENT input. In this state, the supply cur-rent drops to less than 25µA and the receivers continue to operate in a low-power receive mode. Driver outputs enter a high-impedance state (three-state mode). On the MAX225‚ all five receivers are controlled by the ENR input. On the MAX245‚ eight of the receiver out-puts are controlled by the ENR input‚ while the remain-ing two receivers (RA5 and RB5) are always active.RA1–RA4 and RB1–RB4 are put in a three-state mode when ENR is a logic high.Receiver and Transmitter EnableControl InputsThe MAX225 and MAX245–MAX249 feature transmitter and receiver enable controls.The receivers have three modes of operation: full-speed receive (normal active)‚ three-state (disabled)‚ and low-power receive (enabled receivers continue to function at lower data rates). The receiver enable inputs control the full-speed receive and three-state modes. The transmitters have two modes of operation: full-speed transmit (normal active) and three-state (disabled). The transmitter enable inputs also control the shutdown mode. The device enters shutdown mode when all transmitters are disabled. Enabled receivers function in the low-power receive mode when in shutdown.M A X 220–M A X 249Tables 1a–1d define the control states. The MAX244has no control pins and is not included in these tables. The MAX246 has ten receivers and eight drivers with two control pins, each controlling one side of the device. A logic high at the A-side control input (ENA )causes the four A-side receivers and drivers to go into a three-state mode. Similarly, the B-side control input (ENB ) causes the four B-side drivers and receivers to go into a three-state mode. As in the MAX245, one A-side and one B-side receiver (RA5 and RB5) remain active at all times. The entire device is put into shut-down mode when both the A and B sides are disabled (ENA = ENB = +5V).The MAX247 provides nine receivers and eight drivers with four control pins. The ENRA and ENRB receiver enable inputs each control four receiver outputs. The ENTA and ENTB transmitter enable inputs each control four drivers. The ninth receiver (RB5) is always active.The device enters shutdown mode with a logic high on both ENTA and ENTB .The MAX248 provides eight receivers and eight drivers with four control pins. The ENRA and ENRB receiver enable inputs each control four receiver outputs. The ENTA and ENTB transmitter enable inputs control four drivers each. This part does not have an always-active receiver. The device enters shutdown mode and trans-mitters go into a three-state mode with a logic high on both ENTA and ENTB .The MAX249 provides ten receivers and six drivers with four control pins. The ENRA and ENRB receiver enable inputs each control five receiver outputs. The ENTA and ENTB transmitter enable inputs control three dri-vers each. There is no always-active receiver. The device enters shutdown mode and transmitters go into a three-state mode with a logic high on both ENTA and ENTB . In shutdown mode, active receivers operate in a low-power receive mode at data rates up to 20kbits/sec.__________Applications InformationFigures 5 through 25 show pin configurations and typi-cal operating circuits. In applications that are sensitive to power-supply noise, V CC should be decoupled to ground with a capacitor of the same value as C1 and C2 connected as close as possible to the device.Drivers/Receivers16______________________________________________________________________________________。
