General DescriptionThe MAX4051/MAX4052/MAX4053 and MAX4051A/MAX4052A/MAX4053A are low-voltage, CMOS analog ICs configured as an 8-channel multiplexer (MAX4051/A),two 4-channel multiplexers (MAX4052/A), and three sin-gle-pole/double-throw (SPDT) switches (MAX4053/A).The A-suffix parts are fully characterized for on-resistance match, on-resistance flatness, and low leakage.These CMOS devices can operate continuously with dual power supplies ranging from ±2.7V to ±8V or a single supply between +2.7V and +16V. Each switch can handle rail-to-rail analog signals. The off-leakage current is only 0.1nA at +25°C or 5nA at +85°C (MAX4051A/MAX4052A/MAX4053A).All digital inputs have 0.8V to 2.4V logic thresholds,ensuring TTL/CMOS-logic compatibility when using ±5V or a single +5V supply.________________________ApplicationsBattery-Operated Equipment Audio and Video Signal Routing Low-Voltage Data-Acquisition Systems Communications Circuits____________________________Features♦Pin Compatible with Industry-Standard74HC4051/74HC4052/74HC4053♦Guaranteed On-Resistance:100Ωwith ±5V Supplies♦Guaranteed Match Between Channels:6Ω(MAX4051A–MAX4053A)12Ω(MAX4051–MAX4053)♦Guaranteed Low Off-Leakage Currents:0.1nA at +25°C (MAX4051A–MAX4053A)1nA at +25°C (MAX4051–MAX4053)♦Guaranteed Low On-Leakage Currents:0.1nA at +25°C (MAX4051A–MAX4053A)1nA at +25°C (MAX4051–MAX4053)♦Single-Supply Operation from +2.0V to +16V Dual-Supply Operation from ±2.7V to ±8V ♦TTL/CMOS-Logic Compatible ♦Low Distortion: < 0.04% (600Ω)♦Low Crosstalk: < -90dB (50Ω)♦High Off-Isolation: < -90dB (50Ω)MAX4051/A, MAX4052/A, MAX4053/ALow-Voltage, CMOS AnalogMultiplexers/Switches________________________________________________________________Maxim Integrated Products1___________________________________Pin Configurations/Functional Diagrams19-0463; Rev 2; 10/05Ordering Information continued at end of data sheet.For pricing, delivery, and ordering information,please contact Maxim/Dallas Direct!at 1-888-629-4642, or visit Maxim’s website at .M A X 4051/A , M A X 4052/A , M A X 4053/ALow-Voltage, CMOS Analog Multiplexers/Switches 2_______________________________________________________________________________________ABSOLUTE MAXIMUM RATINGSELECTRICAL CHARACTERISTICS—Dual Supplies(V+ = +4.5V to +5.5V, V- = -4.5V to -5.5V, T A = T MIN to T MAX , unless otherwise noted.

They have three supply pins:V+, V-, and GND. V+ and V- are used to drive the inter-nal CMOS switches and set the limits of the analog volt-age on any switch. Reverse ESD-protection diodes are internally connected between each analog signal pin and both V+ and V-. If any analog signal exceeds V+ or V-, one of these diodes will conduct. During normal operation, these (and other) reverse-biased ESD diodes leak, forming the only current drawn from V+ or V-.Virtually all the analog leakage current comes from the ESD diodes. Although the ESD diodes on a given signal pin are identical, and therefore fairly well balanced,they are reverse biased differently. Each is biased by either V+ or V- and the analog signal. This means their leakages will vary as the signal varies. The difference in the two diode leakages to the V+ and V- pins consti-tutes the analog signal path leakage current. All analog leakage current flows between each pin and one of the supply terminals, not to the other switch terminal. This is why both sides of a given switch can show leakage cur-rents of either the same or opposite polarity.There is no connection between the analog signal paths and GND.MAX4051/A, MAX4052/A, MAX4053/AMultiplexers/Switches______________________________________________________________________________________11Table 1. Truth Table/Switch ProgrammingX = Don’t care * ADDC not present on MAX4052.Note:NO and COM pins are identical and interchangeable. Either may be considered an input or output; signals pass equally wellin either direction.M A X 4051/A , M A X 4052/A , M A X 4053/AV+ and G ND power the internal logic and logic-level translators, and set both the input and output logic lim-its. The logic-level translators convert the logic levels into switched V+ and V- signals to drive the gates of the analog signals. This drive signal is the only connec-tion between the logic supplies (and signals) and the analog supplies. V+ and V- have ESD-protection diodes to GND.The logic-level thresholds are TTL/CMOS compatible when V+ is +5V. As V+ rises, the threshold increases slightly, so when V+ reaches +12V, the threshold is about 3.1V; above the TTL-guaranteed high-level mini-mum of 2.8V, but still compatible with CMOS outputs.Bipolar SuppliesThese devices operate with bipolar supplies between ±3.0V and ±8V. The V+ and V- supplies need not be symmetrical, but their sum cannot exceed the absolute maximum rating of +17V.Single SupplyThese devices operate from a single supply between +3V and +16V when V- is connected to GND. All of the bipolar precautions must be observed. At room temper-ature, they actually “work” with a single supply at near or below +1.7V, although as supply voltage decreases,switch on-resistance and switching times become very high.Overvoltage ProtectionProper power-supply sequencing is recommended for all CMOS devices. Do not exceed the absolute maxi-mum ratings, because stresses beyond the listed rat-ings can cause permanent damage to the devices.Always sequence V+ on first, then V-, followed by the logic inputs (NO) and by COM. If power-supply sequencing is not possible, add two small signal diodes (D1, D2) in series with the supply pins for overvoltage protection (Figure 1).Adding diodes reduces the analog signal range to one diode drop below V+ and one diode drop above V-, but does not affect the devices’ low switch resistance and low leakage characteristics. Device operation is unchanged, and the difference between V+ and V-should not exceed 17V. These protection diodes are not recommended when using a single supply if signal levels must extend to ground.High-Frequency PerformanceIn 50Ωsystems, signal response is reasonably flat up to 50MHz (see Typical Operating Characteristics ).Above 20MHz, the on response has several minor peaks which are highly layout dependent. The problem is not turning the switch on, but turning it off. The off-state switch acts like a capacitor, and passes higher frequencies with less attenuation. At 10MHz, off isola-tion is about -45dB in 50Ωsystems, becoming worse (approximately 20dB per decade) as frequency increases. Higher circuit impedances also make off iso-lation worse. Adjacent channel attenuation is about 3dB above that of a bare IC socket, and is entirely due to capacitive coupling.Multiplexers/Switches 12______________________________________________________________________________________Figure 1.

Each part contains one driver and one receiver. The MAX483, MAX487, MAX488, and MAX489feature reduced slew-rate drivers that minimize EMI and reduce reflections caused by improperly terminated cables,thus allowing error-free data transmission up to 250kbps.The driver slew rates of the MAX481, MAX485, MAX490,MAX491, and MAX1487 are not limited, allowing them to transmit up to 2.5Mbps.These transceivers draw between 120µA and 500µA of supply current when unloaded or fully loaded with disabled drivers. Additionally, the MAX481, MAX483, and MAX487have a low-current shutdown mode in which they consume only 0.1µA. All parts operate from a single 5V supply.Drivers are short-circuit current limited and are protected against excessive power dissipation by thermal shutdown circuitry that places the driver outputs into a high-imped-ance state. The receiver input has a fail-safe feature that guarantees a logic-high output if the input is open circuit.The MAX487 and MAX1487 feature quarter-unit-load receiver input impedance, allowing up to 128 MAX487/MAX1487 transceivers on the bus. Full-duplex communi-cations are obtained using the MAX488–MAX491, while the MAX481, MAX483, MAX485, MAX487, and MAX1487are designed for half-duplex applications.________________________ApplicationsLow-Power RS-485 Transceivers Low-Power RS-422 Transceivers Level TranslatorsTransceivers for EMI-Sensitive Applications Industrial-Control Local Area Networks__Next Generation Device Features♦For Fault-Tolerant ApplicationsMAX3430: ±80V Fault-Protected, Fail-Safe, 1/4Unit Load, +3.3V, RS-485 TransceiverMAX3440E–MAX3444E: ±15kV ESD-Protected,±60V Fault-Protected, 10Mbps, Fail-Safe, RS-485/J1708 Transceivers♦For Space-Constrained ApplicationsMAX3460–MAX3464: +5V, Fail-Safe, 20Mbps,Profibus RS-485/RS-422 TransceiversMAX3362: +3.3V, High-Speed, RS-485/RS-422Transceiver in a SOT23 PackageMAX3280E–MAX3284E: ±15kV ESD-Protected,52Mbps, +3V to +5.5V, SOT23, RS-485/RS-422,True Fail-Safe ReceiversMAX3293/MAX3294/MAX3295: 20Mbps, +3.3V,SOT23, RS-855/RS-422 Transmitters ♦For Multiple Transceiver ApplicationsMAX3030E–MAX3033E: ±15kV ESD-Protected,+3.3V, Quad RS-422 Transmitters ♦For Fail-Safe ApplicationsMAX3080–MAX3089: Fail-Safe, High-Speed (10Mbps), Slew-Rate-Limited RS-485/RS-422Transceivers♦For Low-Voltage ApplicationsMAX3483E/MAX3485E/MAX3486E/MAX3488E/MAX3490E/MAX3491E: +3.3V Powered, ±15kV ESD-Protected, 12Mbps, Slew-Rate-Limited,True RS-485/RS-422 TransceiversMAX481/MAX483/MAX485/MAX487–MAX491/MAX1487Low-Power, Slew-Rate-Limited RS-485/RS-422 Transceivers______________________________________________________________Selection Table19-0122; Rev 8; 10/03Ordering Information appears at end of data sheet.M A X 481/M A X 483/M A X 485/M A X 487–M A X 491/M A X 1487Low-Power, Slew-Rate-Limited RS-485/RS-422 Transceivers 2_______________________________________________________________________________________ABSOLUTE MAXIMUM RATINGSSupply Voltage (V CC ).............................................................12V Control Input Voltage (RE , DE)...................-0.5V to (V CC + 0.5V)Driver Input Voltage (DI).............................-0.5V to (V CC + 0.5V)Driver Output Voltage (A, B)...................................-8V to +12.5V Receiver Input Voltage (A, B).................................-8V to +12.5V Receiver Output Voltage (RO).....................-0.5V to (V CC +0.5V)Continuous Power Dissipation (T A = +70°C)8-Pin Plastic DIP (derate 9.09mW/°C above +70°C)....727mW 14-Pin Plastic DIP (derate 10.00mW/°C above +70°C)..800mW 8-Pin SO (derate 5.88mW/°C above +70°C).................471mW14-Pin SO (derate 8.33mW/°C above +70°C)...............667mW 8-Pin µMAX (derate 4.1mW/°C above +70°C)..............830mW 8-Pin CERDIP (derate 8.00mW/°C above +70°C).........640mW 14-Pin CERDIP (derate 9.09mW/°C above +70°C).......727mW Operating Temperature RangesMAX4_ _C_ _/MAX1487C_ A...............................0°C to +70°C MAX4__E_ _/MAX1487E_ A.............................-40°C to +85°C MAX4__MJ_/MAX1487MJA...........................-55°C to +125°C Storage Temperature Range.............................-65°C to +160°C Lead Temperature (soldering, 10sec).............................+300°CDC ELECTRICAL CHARACTERISTICS(V CC = 5V ±5%, T A = T MIN to T MAX , unless otherwise noted.)

The MAX481, MAX485, MAX490,MAX491, and MAX1487 can transmit and receive at data rates up to 2.5Mbps, while the MAX483, MAX487,MAX488, and MAX489 are specified for data rates up to 250kbps. The MAX488–MAX491 are full-duplex trans-ceivers while the MAX481, MAX483, MAX485, MAX487,and MAX1487 are half-duplex. In addition, Driver Enable (DE) and Receiver Enable (RE) pins are included on the MAX481, MAX483, MAX485, MAX487, MAX489,MAX491, and MAX1487. When disabled, the driver and receiver outputs are high impedance.MAX487/MAX1487:128 Transceivers on the BusThe 48k Ω, 1/4-unit-load receiver input impedance of the MAX487 and MAX1487 allows up to 128 transceivers on a bus, compared to the 1-unit load (12k Ωinput impedance) of standard RS-485 drivers (32 trans-ceivers maximum). Any combination of MAX487/MAX1487 and other RS-485 transceivers with a total of 32 unit loads or less can be put on the bus. The MAX481/MAX483/MAX485 and MAX488–MAX491 have standard 12k ΩReceiver Input impedance.Low-Power, Slew-Rate-Limited RS-485/RS-422 Transceivers 8_______________________________________________________________________________________Figure 2.

Figure 12 shows the dri-ver output waveform and its Fourier analysis of a 150kHz signal transmitted by a MAX481, MAX485,MAX490, MAX491, or MAX1487. High-frequency har-monics with large amplitudes are evident. Figure 13shows the same information displayed for a MAX483,MAX487, MAX488, or MAX489 transmitting under the same conditions. Figure 13’s high-frequency harmonics have much lower amplitudes, and the potential for EMI is significantly reduced.MAX481/MAX483/MAX485/MAX487–MAX491/MAX1487Low-Power, Slew-Rate-Limited RS-485/RS-422 Transceivers_______________________________________________________________________________________9_________________________________________________________________Test CircuitsFigure 4.

Receiver Enable and Disable Times (except MAX488and MAX490)Table 1. TransmittingTable 2. ReceivingLow-Power Shutdown Mode (MAX481/MAX483/MAX487)A low-power shutdown mode is initiated by bringing both RE high and DE low. The devices will not shut down unless both the driver and receiver are disabled.In shutdown, the devices typically draw only 0.1µA of supply current.RE and DE may be driven simultaneously; the parts are guaranteed not to enter shutdown if RE is high and DE is low for less than 50ns. If the inputs are in this state for at least 600ns, the parts are guaranteed to enter shutdown.For the MAX481, MAX483, and MAX487, the t ZH and t ZL enable times assume the part was not in the low-power shutdown state (the MAX485/MAX488–MAX491and MAX1487 can not be shut down). The t ZH(SHDN)and t ZL(SHDN)enable times assume the parts were shut down (see Electrical Characteristics ).It takes the drivers and receivers longer to become enabled from the low-power shutdown state (t ZH(SHDN ), t ZL(SHDN)) than from the operating mode (t ZH , t ZL ). (The parts are in operating mode if the –R —E –,DE inputs equal a logical 0,1 or 1,1 or 0, 0.)Driver Output ProtectionExcessive output current and power dissipation caused by faults or by bus contention are prevented by two mechanisms. A foldback current limit on the output stage provides immediate protection against short cir-cuits over the whole common-mode voltage range (see Typical Operating Characteristics ). In addition, a ther-mal shutdown circuit forces the driver outputs into a high-impedance state if the die temperature rises excessively.Propagation DelayMany digital encoding schemes depend on the differ-ence between the driver and receiver propagation delay times. Typical propagation delays are shown in Figures 15–18 using Figure 14’s test circuit.The difference in receiver delay times, | t PLH - t PHL |, is typically under 13ns for the MAX481, MAX485,MAX490, MAX491, and MAX1487 and is typically less than 100ns for the MAX483 and MAX487–MAX489.The driver skew times are typically 5ns (10ns max) for the MAX481, MAX485, MAX490, MAX491, and MAX1487, and are typically 100ns (800ns max) for the MAX483 and MAX487–MAX489.MAX481/MAX483/MAX485/MAX487–MAX491/MAX1487Low-Power, Slew-Rate-Limited RS-485/RS-422 Transceivers______________________________________________________________________________________1110dB/div0Hz5MHz500kHz/div10dB/div0Hz5MHz500kHz/divFigure 12.

For line lengths greater than 4000 feet, see Figure 23.Figures 19 and 20 show the system differential voltage for the parts driving 4000 feet of 26AWG twisted-pair wire at 110kHz into 120Ωloads.Typical ApplicationsThe MAX481, MAX483, MAX485, MAX487–MAX491, and MAX1487 transceivers are designed for bidirectional data communications on multipoint bus transmission lines.Figures 21 and 22 show typical network applications circuits. These parts can also be used as line repeaters, with cable lengths longer than 4000 feet, as shown in Figure 23.To minimize reflections, the line should be terminated at both ends in its characteristic impedance, and stub lengths off the main line should be kept as short as possi-ble. The slew-rate-limited MAX483 and MAX487–MAX489are more tolerant of imperfect termination.MAX481/MAX483/MAX485/MAX487–MAX491/MAX1487Low-Power, Slew-Rate-Limited RS-485/RS-422 Transceivers______________________________________________________________________________________13DIV Y -V ZRO5V 0V1V0V -1V5V 0V2µs/divFigure 19.

HIP4081A80V/2.5A Peak, High FrequencyFull Bridge FET DriverDescriptionThe HIP4081A is a high frequency, medium voltage Full Bridge N-Channel FET driver IC, available in 20 lead plastic SOIC and DIP packages. The HIP4081A can drive every possible switch combination except those which would cause a shoot-through condition. The HIP4081A can switch at frequencies up to 1MHz and is well suited to driving Voice Coil Motors, high-frequency Class D audio amplifiers, and power supplies.For example, the HIP4081A can drive medium voltage brush motors, and two HIP4081As can be used to drive high per-formance stepper motors, since the short minimum “on-time”can provide fine micro-stepping capability.Short propagation delays of approximately 55ns maximizes control loop crossover frequencies and dead-times which can be adjusted to near zero to minimize distortion, resulting in rapid, precise control of the driven load.A similar part, the HIP4080A, includes an on-chip input com-parator to create a PWM signal from an external triangle wave and to facilitate “hysteresis mode” switching.The Application Note for the HIP4081A is the AN9405.Ordering InformationPART NUMBER TEMP RANGE(o C)PACKAGE PKG.

External bootstrap diode and capacitor are required. Connect cathode of boot-strap diode and positive side of bootstrap capacitor to this pin. Internal charge pump supplies 30µA out of thispin to maintain bootstrap supply. Internal circuitry clamps the bootstrap supply to approximately 12.8V.2BHI B High-side Input. Logic level input that controls BHO driver (Pin 20). BLI (Pin 5) high level input overrides BHI high level input to prevent half-bridge shoot-through, see T ruth T able. DIS (Pin 3) high level input overrides BHIhigh level input. The pin can be driven by signal levels of 0V to 15V (no greater than V DD). An internal 100µApull-up to V DD will hold BHI high, so no connection is required if high-side and low-side outputs are to be con-trolled by the low-side input.3DIS DISable input. Logic level input that when taken high sets all four outputs low. DIS high overrides all other inputs.When DIS is taken low the outputs are controlled by the other inputs. The pin can be driven by signal levels of0V to 15V (no greater than V DD). An internal 100µA pull-up to V DD will hold DIS high if this pin is not driven.4V SS Chip negative supply, generally will be ground.5BLI B Low-side Input. Logic level input that controls BLO driver (Pin 18). If BHI (Pin 2) is driven high or not connected externally then BLI controls both BLO and BHO drivers, with dead time set by delay currents at HDEL and LDEL(Pin 8 and 9). DIS (Pin 3) high level input overrides BLI high level input. The pin can be driven by signal levelsof 0V to 15V (no greater than V DD). An internal 100µA pull-up to V DD will hold BLI high if this pin is not driven.6ALI A Low-side Input. Logic level input that controls ALO driver (Pin 13). If AHI (Pin 7) is driven high or not connected externally then ALI controls both ALO and AHO drivers, with dead time set by delay currents at HDEL and LDEL(Pin 8 and 9). DIS (Pin 3) high level input overrides ALI high level input. The pin can be driven by signal levelsof 0V to 15V (no greater than V DD). An internal 100µA pull-up to V DD will hold ALI high if this pin is not driven.7AHI A High-side Input. Logic level input that controls AHO driver (Pin 11). ALI (Pin 6) high level input overrides AHI high level input to prevent half-bridge shoot-through, see T ruth T able. DIS (Pin 3) high level input overrides AHIhigh level input. The pin can be driven by signal levels of 0V to 15V (no greater than V DD). An internal 100µApull-up to V DD will hold AHI high, so no connection is required if high-side and low-side outputs are to be con-trolled by the low-side input.8HDEL High-side turn-on DELay. Connect resistor from this pin to V SS to set timing current that defines the turn-on de-lay of both high-side drivers. The low-side drivers turn-off with no adjustable delay, so the HDEL resistor guar-antees no shoot-through by delaying the turn-on of the high-side drivers. HDEL reference voltage isapproximately 5.1V.9LDEL Low-side turn-on DELay. Connect resistor from this pin to V SS to set timing current that defines the turn-on delay of both low-side drivers. The high-side drivers turn-off with no adjustable delay, so the LDEL resistor guaranteesno shoot-through by delaying the turn-on of the low-side drivers. LDEL reference voltage is approximately 5.1V.10AHB A High-side Bootstrap supply. External bootstrap diode and capacitor are required.
