±15kV ESD-Protected, Slew-Rate-Limited,Low-Power, RS-485/RS-422 Transceivers ______________________________________________________________Pin DescriptionMAX481E/MAX483E/MAX485E/MAX487E–MAX491E/MAX1487E7±15kV ESD-Protected, Slew-Rate-Limited,Low-Power, RS-485/RS-422 Transceivers__________Function Tables (MAX481E/MAX483E/MAX485E/MAX487E/MAX1487E) Table 1. Transmitting Table 2. Receiving__________Applications Information The MAX481E/MAX483E/MAX485E/MAX487E–MAX491E and MAX1487E are low-power transceivers for RS-485 and RS-422 communications. These “E” versions of the MAX481, MAX483, MAX485, MAX487–MAX491, and MAX1487 provide extra protection against ESD. The rugged MAX481E, MAX483E, MAX485E, MAX497E–MAX491E, and MAX1487E are intended for harsh envi-ronments where high-speed communication is important. These devices eliminate the need for transient suppres-sor diodes and the associated high capacitance loading. The standard (non-“E”) MAX481, MAX483, MAX485, MAX487–MAX491, and MAX1487 are recommended for applications where cost is critical.The MAX481E, MAX485E, MAX490E, MAX491E, and MAX1487E can transmit and receive at data rates up to 2.5Mbps, while the MAX483E, MAX487E, MAX488E, and MAX489E are specified for data rates up to 250kbps. The MAX488E–MAX491E are full-duplex transceivers, while the MAX481E, MAX483E, MAX487E, and MAX1487E are half-duplex. In addition, driver-enable (DE) and receiver-enable (RE) pins are included on the MAX481E, MAX483E, MAX485E, MAX487E, MAX489E, MAX491E, and MAX1487E. When disabled, the driver and receiver outputs are high impedance.±15kV ESD Protection As with all Maxim devices, ESD-protection structures are incorporated on all pins to protect against electro-static discharges encountered during handling and assembly. The driver outputs and receiver inputs have extra protection against static electricity. Maxim’s engi-neers developed state-of-the-art structures to protect these pins against ESD of ±15kV without damage. The ESD structures withstand high ESD in all states: normal operation, shutdown, and powered down. After an ESD event, Maxim’s MAX481E, MAX483E, MAX485E, MAX487E–MAX491E, and MAX1487E keep working without latchup.ESD protection can be tested in various ways; the transmitter outputs and receiver inputs of this product family are characterized for protection to ±15kV using the Human Body Model.Other ESD test methodologies include IEC10004-2 con-tact discharge and IEC1000-4-2 air-gap discharge (for-merly IEC801-2).ESD Test Conditions ESD performance depends on a variety of conditions. Contact Maxim for a reliability report that documents test set-up, test methodology, and test results.Human Body Model F igure 4 shows the Human Body Model, and F igure 5 shows the current waveform it generates when dis-charged into a low impedance. This model consists of a 100pF capacitor charged to the ESD voltage of inter-est, which is then discharged into the test device through a 1.5kΩresistor.IEC1000-4-2 The IEC1000-4-2 standard covers ESD testing and per-formance of finished equipment; it does not specifically refer to integrated circuits (Figure 6).MAX481E/MAX483E/MAX485E/MAX487E–MAX491E/MAX1487E Maxim Integrated9。

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.

Yo u no w o wn a very unique signal processing device with no equal in the audio world. Whether you purchased the BBE 482 for your home studio, P.A., DJ system, or instrument rack, you will find the 482's rugged construction and careful electronic design a welcome addition to your sonic arsenal.Thank yo u fo r yo ur purchase, and fo r the trust that yo u've placed in BBE. We are co mmitted to bringing you the finest products, with useful and unique features to serve your audio needs.The BBE Process—"What it Is"Loudspeakers have difficulty working with the electronic signals supplied by an amplifier. These difficulties cause such major phase and amplitude distortion that the sound reproduced by speaker differs significantly from the sound produced by the original source.In the past, these problems proved unsolvable and were thus delegated to a position of secondary importance in audio system design. However, phase and amplitude integrity is essential to accurate sound reproduction. Research shows that the information which the listener translates into the recognizable characteristics of a live performance are intimately tied into complex time and amplitude relationships between the fundamental and harmonic componentsof a given musical note or sound. These relationships define a sound's “sound”.When these complex relationships pass through a speaker, the proper order is lost. The higher frequencies are delayed.A lower frequency may reach the listener's ear first or perhaps simultaneously with that of a higher frequency. In some cases, the fundamental components may be so time-shifted that they reach the listener's ear ahead of some or all of the harmonic components.This change in the phase and amplitude relationship on the harmonic and fundamental frequencies is technically called “envelope distortion.” The listener perceives this loss of sound integrity in the reproduced sound as "muddy" and “smeared.” In the extreme, it can become difficult to tell the difference between musical instruments, for example,an oboe and a clarinet.BBE Sound, Inc. conducted extensive studies of numerous speaker systems over a ten year period. With this knowledge,it became possible to identify the characteristics of an ideal speaker and to distill the corrections necessary to return the fundamental and harmonic frequency structures to their correct order. While there are differences among various speaker designs in the magnitude of their correction, the overall pattern of correction needed is remarkably consistent.The BBE Process is so unique that 42 patents have been awarded by the U.S. Patent Office.Product DescriptionThe BBE 482 is a dual channel, single rack space device for use in -l0dBu line level applications. For each channel there are one pair of Lo Contour and Process knobs plus a 5 segment LED input level meter. A single function button switches the BBE process on or off in both channels, which is useful for comparing the processed sound to the unprocessed sound. An LED next to the function button glows green when the BBE process is on and red when the process is off. The Lo Contour controls are for adjusting the level of phase corrected low frequencies in the program material. The Process controls are for adjusting the level of phase corrected high frequencies in the program material. Things to RememberThe BBE 482 is designed to work with -l0dBu line levels. This is suitable for professional and semi-pro mixers, P.A.consoles, recording studios, or D.J. equipment. The BBE 482 drives load impedances down to 1K Ohm and supplies a maximum output level of +18dBu. Plugging a guitar or other high impedance device directly into the BBE 482 will not work properly as its input impedance is less than 50K ohms.Set-UpThe BBE 482 is connected into the chain in series with the signal path the same way a graphic equalizer or limiter would be connected. The output of a mixer, pre-amp, or other sound source feeds the input of the BBE 482. Setting up the BBE 482 as an echo send device like a digital reverb is not recommended as the processed effect is not fully realized when summed with the original source audio.APPLICATIONSMusic and P.A. SystemsThe BBE 482 is a welcome addition to any live sound P.A. system because the BBE circuit dramatically improves the clarity and intelligibility of vocals and musical instruments. Night club and mobile DJ systems will also benefit greatly from the BBE Process, with more depth, detail and punch over the entire mix. The 482 can be hooked up to any P.A.or DJ sound system exactly like an equalizer would. When using in conjunction with an equalizer, the 482 should be added after the equalizer in the signal chain. In the event that the equalizer is being used for drastic tone alteration, then insert the 482 before the equalizer in the signal chain. Placement either before or after an equalizer should have no negative effect on the 482 unit or its processing ability, however most users find they prefer more modest use of their equalizers once the BBE 482 has been added to their sound systems.Instrument RacksThe BBE 482 will deliver surprisingly good results in guitar, bass and keyboard rack systems. Electric guitars have added “bite”, “chunk” and improved definition. As Guitar Player magazine said, “BBE is the most cost effective improvement you can add to your rig”. Acoustic guitars processed with the 482 have a breathtakingly natural sparkle and presence.Bassists will delight in the BBE 482's ability to bring much more punch to the bottom end without muddying up the midrange. The 482 is also great for keyboard rigs, with everything from the latest samples to a vintage Rhodes benefiting equally from the patented BBE process.Recording SystemsThe BBE 482 can be used as an effect on individual tracks or applied overall during mixdown. The BBE process works very well to liven up the final mix, which is why the BBE 482 and 882 models are popular for use in both recreational and professional recording studios.FRONT PANEL CONTROLSpanel corresponds to the output signal level, measured in decibels. Example: The “0” indicates a 0dBu signal level,“-6” refers to -6dBu, and so on. Once an input signal level has been established, increasing the BBE PROCESS and LO CONTOUR will increase the output signal and cause more LEDs to illuminate. The Clip LED monitors the input signal level. The Clip LED will illuminate at +15dBu, giving a 3dBu warning of the impending distortion at +18dBu, the actual clip point.2. LO CONTOUR: Regulates the amount of phase corrected bass frequencies.3. PROCESS:Regulates the amount of phase corrected treble frequencies.4. BBE FU NCTION: This push button switch allows for quick comparison of processed with unprocessed sound.When the switch is pushed in, the process is on and the indicator LED is green. When the switch is out, the process is off and the indicator LED is red.5.

OUTPUT: The output of the BBE 482 can be taken from the 1/4” Phone Jack or the RCA Jack. Both are unbalancedand are the same point electronically. This allows both outputs to be used simultaneously, eliminating the need fora “Y” cord in the event multiple outputs are required. The recommended single load impedance is at least 10kOhms. If both outputs are being used, a minimum of a 22k Ohm load per device is required. (The “load” is determined by the input impedance of the next subsequent component in the signal chain.) The maximum output is rated at +18dBu. The output impedance of the BBE 482 is 1 k ohms. NOTE: Actual output level will vary due to the selected position of the BBE Process, and the actual input signal level.4.INPUT: The input of the BBE 482 is an unbalanced connection. Although is can be either a 1/4” Phone Plug or anRCA Plug, it is recommended that only one input source is used. Both jacks are the same point electronically, however, due to the input/output impedance characteristics of most audio devices, a loss of signal may occur and/or damage to a component if both inputs are utilized. The input impedance of th BBE 482 is 47k Ohms. The maximum signal level is +18dBu.5.CHANNEL A: These connections function the same as CHANNEL B.SpecificationsFrequency Response,process mode:……………………………Program controlledbypass mode:……………………………10Hz to 50kHz +/-0.5dBu, -10dBu inputTHD,process mode:……………………………less than 0.025% at -10dBu input, 20-20kHzbypass mode:……………………………less than 0.002% at -l0dBu input, 20-20kHz Maximum Output:………………………………+18dBu (may vary due to control settings)Input Impedance:………………………………47k Ohms, unbalanced 1/4"phone jack or RCA jackOutput Impedance:……………………………1 k Ohms, unbalanced 1/4"phone jack or RCA jackSensitivity:…………………………………………-45dBu for maximum processMaximum Process:………………………………+12dBu boost at 5kHz, -l0dBu inputLo Contour:………………………………………+12dBu boost at 50Hz, -l0dBu input* 0dBu = 0.775mVrmsPower Requirements:……………………………U.S., Canada 8 Japan models: 120VAC, 50/60Hz, 8 WATTSStandard model: 220VAC, 50/60Hz, 8 WATTS Fuse:………………………………………………Replace with the same type FASTBLOW fuseU.S., Canada & Japan models: 250Vac, 1 /2A Fast blow type fuse.Standard model: 250Vac, .125A Fastblow type fuse Dimensions: …………………………………......19"(W) x 5.5"(D) x 1.7"(H)Shipping Weight:………………………………6.5 lbs.Note: Due to continuing product improvement, specifications and design are subject to change without notice. General OperationTHE BBE 482 IS A LINE LEVEL SIGNAL PROCESSOR AND IS TO BE CONNECTED PRIOR TO THE POWER AMP IN ANY AUDIO SYSTEM. SIGNIFICANT DAMAGE MAY BE INFLICTED TO THE BBE 482 OR ANY SUBSEQUENT COMPONENT IN THE SYSTEM IN THE EVENT THE OUTPUT OF A POWER AMP IS CONNECTED DIRECTLY TO THE INPUT OF THE BBE 482.In order to reduce the risk of damage to any equipment, properly connect all cables and power cables before turning on any components in the system. Most important of all, ALWAYS TURN ON THE POWER AMPLIFIER LAST TO AVOID DAMAGING THE SPEAKERS OR THE AMP.The BBE 482 may be utilized in a number of different environments and its results may vary accordingly. Because both channels are completely independent from each other, only one channel of the BBE 482 may be used, or each channel processing a different signal source. The effects loop is the ideal placement in the signal chain ofa guitar application. In a pre-amp, keyboard or P.A. application, the BBE 482 works best as the last componentin the signal chain, just before the crossover or power amp. Important: In a P.A. application, never connect the BBE 482 into the effects loop. The inherent phase shift of the BBE Process will cause phase cancellation resulting in a partial loss of signal.BBE and EqualizationThe most common question asked of the BBE Sound, Inc. service department is: “Where does the BBE Processor connect in the signal chain, before or after the equalizer?” Many people find that the same amount of equalization is no longer needed, if at all, when a BBE processor is used. Additionally, the amount of equalization used will help determine the BBE 482’s proper location in the signal chain: If the EQ is being set to give the rooma flat response as determined by a spectrum analyzer, the BBE 482 will work properly before or after the EQ.(Placing the BBE 482 after the EQ is recommended.) If the EQ is being used for drastic tone alteration, the recommended placement would be before the EQ. Neither of these configurations will harm the BBE 482.LIVE APPLICATION: NON-POWERED MIXER Connect the BBE 482 to the output of the mixing console. The output of the BBE will drive either a crossover or a power amplifier directly.MICROPHONESPA CABINET PA CABINETPOWER AMPLIFIER KEYBOARDMIXING CONSOLEBBE 482 SONIC MAXIMIZER CASSETTE DECKLIVE APPLICATION: POWERED MIXERThere are a couple of ways to configure the BBE 482 into a powered mixer.
