General DescriptionThe MAX13080E–MAX13089E +5.0V, ±15kV ESD-protect-ed, RS-485/RS-422 transceivers feature one driver and one receiver. These devices include fail-safe circuitry,guaranteeing a logic-high receiver output when receiver inputs are open or shorted. The receiver outputs a logic-high if all transmitters on a terminated bus are disabled (high impedance). The MAX13080E–MAX13089E include a hot-swap capability to eliminate false transitions on the bus during power-up or hot insertion.The MAX13080E/MAX13081E/MAX13082E feature reduced slew-rate drivers that minimize EMI and reduce reflections caused by improperly terminated cables, allowing error-free data transmission up to 250kbps. The MAX13083E/MAX13084E/MAX13085E also feature slew-rate-limited drivers but allow transmit speeds up to 500kbps. The MAX13086E/MAX13087E/MAX13088E driver slew rates are not limited, making transmit speeds up to 16Mbps possible. The MAX13089E slew rate is pin selectable for 250kbps,500kbps, and 16Mbps.The MAX13082E/MAX13085E/MAX13088E are intended for half-duplex communications, and the MAX13080E/MAX13081E/MAX13083E/MAX13084E/MAX13086E/MAX13087E are intended for full-duplex communica-tions. The MAX13089E is selectable for half-duplex or full-duplex operation. It also features independently programmable receiver and transmitter output phase through separate pins.The MAX13080E–MAX13089E transceivers draw 1.2mA of supply current when unloaded or when fully loaded with the drivers disabled. All devices have a 1/8-unit load receiver input impedance, allowing up to 256transceivers on the bus.The MAX13080E/MAX13083E/MAX13086E/MAX13089E are available in 14-pin PDIP and 14-pin SO packages.The MAX13081E/MAX13082E/MAX13084E/MAX13085E/MAX13087E/MAX13088E are available in 8-pin PDIP and 8-pin SO packages.

These devices feature fail-safe circuit-ry, which guarantees a logic-high receiver output when the receiver inputs are open or shorted, or when they are connected to a terminated transmission line with all dri-vers disabled (see the Fail-Safe section). The MAX13080E/MAX13082E/MAX13083E/MAX13085E/ MAX13086E/MAX13088E/MAX13089E also feature a hot-swap capability allowing line insertion without erroneous data transfer (see the Hot Swap Capability section). The MAX13080E/MAX13081E/MAX13082E feature reduced slew-rate drivers that minimize EMI and reduce reflec-tions caused by improperly terminated cables, allowing error-free data transmission up to 250kbps. The MAX13083E/MAX13084E/MAX13085E also offer slew-rate limits allowing transmit speeds up to 500kbps. The MAX13086E/MAX13087E/MAX13088Es’ driver slew rates are not limited, making transmit speeds up to 16Mbps possible. The MAX13089E’s slew rate is selectable between 250kbps, 500kbps, and 16Mbps by driving a selector pin with a three-state driver.The MAX13082E/MAX13085E/MAX13088E are half-duplex transceivers, while the MAX13080E/MAX13081E/ MAX13083E/MAX13084E/MAX13086E/MAX13087E are full-duplex transceivers. The MAX13089E is selectable between half- and full-duplex communication by driving a selector pin (H/F) high or low, respectively.All devices operate from a single +5.0V supply. Drivers are output short-circuit current limited. Thermal-shutdown circuitry protects drivers against excessive power dissi-pation. When activated, the thermal-shutdown circuitry places the driver outputs into a high-impedance state.Receiver Input Filtering The receivers of the MAX13080E–MAX13085E, and the MAX13089E when operating in 250kbps or 500kbps mode, incorporate input filtering in addition to input hysteresis. This filtering enhances noise immunity with differential signals that have very slow rise and fall times. Receiver propagation delay increases by 25% due to this filtering.Fail-Safe The MAX13080E family guarantees a logic-high receiver output when the receiver inputs are shorted or open, or when they are connected to a terminated transmission line with all drivers disabled. This is done by setting the receiver input threshold between -50mV and -200mV. If the differential receiver input voltage (A - B) is greater than or equal to -50mV, RO is logic-high. If (A - B) is less than or equal to -200mV, RO is logic-low. In the case of a terminated bus with all transmitters disabled, the receiv-er’s differential input voltage is pulled to 0V by the termi-nation. With the receiver thresholds of the MAX13080E family, this results in a logic-high with a 50mV minimumnoise margin. Unlike previous fail-safe devices, the-50mV to -200mV threshold complies with the ±200mVEIA/TIA-485 standard.Hot-Swap Capability (Except MAX13081E/MAX13084E/MAX13087E)Hot-Swap InputsWhen circuit boards are inserted into a hot or powered backplane, differential disturbances to the data buscan lead to data errors. Upon initial circuit board inser-tion, the data communication processor undergoes itsown power-up sequence. During this period, the processor’s logic-output drivers are high impedanceand are unable to drive the DE and RE inputs of these devices to a defined logic level. Leakage currents up to±10µA from the high-impedance state of the proces-sor’s logic drivers could cause standard CMOS enableinputs of a transceiver to drift to an incorrect logic level. Additionally, parasitic circuit board capacitance couldcause coupling of V CC or GND to the enable inputs. Without the hot-swap capability, these factors could improperly enable the transceiver’s driver or receiver.When V CC rises, an internal pulldown circuit holds DElow and RE high. After the initial power-up sequence,the pulldown circuit becomes transparent, resetting thehot-swap tolerable input.Hot-Swap Input CircuitryThe enable inputs feature hot-swap capability. At theinput there are two NMOS devices, M1 and M2 (Figure 9). When V CC ramps from zero, an internal 7µstimer turns on M2 and sets the SR latch, which alsoturns on M1. Transistors M2, a 1.5mA current sink, andM1, a 500µA current sink, pull DE to GND through a5kΩresistor. M2 is designed to pull DE to the disabledstate against an external parasitic capacitance up to100pF that can drive DE high. After 7µs, the timer deactivates M2 while M1 remains on, holding DE low against three-state leakages that can drive DE high. M1 remains on until an external source overcomes the required input current. At this time, the SR latch resetsand M1 turns off. When M1 turns off, DE reverts to a standard, high-impedance CMOS input. Whenever V CCdrops below 1V, the hot-swap input is reset.For RE there is a complementary circuit employing two PMOS devices pulling RE to V CC. MAX13080E–MAX13089E+5.0V, ±15kV ESD-Protected, Fail-Safe, Hot-Swap, RS-485/RS-422 TransceiversM A X 13080E –M A X 13089EMAX13089E ProgrammingThe MAX13089E has several programmable operating modes. Transmitter rise and fall times are programma-ble, resulting in maximum data rates of 250kbps,500kbps, and 16Mbps. To select the desired data rate,drive SRL to one of three possible states by using a three-state driver: V CC , GND, or unconnected. F or 250kbps operation, set the three-state device in high-impedance mode or leave SRL unconnected. F or 500kbps operation, drive SRL high or connect it to V CC .F or 16Mbps operation, drive SRL low or connect it to GND. SRL can be changed during operation without interrupting data communications.Occasionally, twisted-pair lines are connected backward from normal orientation. The MAX13089E has two pins that invert the phase of the driver and the receiver to cor-rect this problem. F or normal operation, drive TXP and RXP low, connect them to ground, or leave them uncon-nected (internal pulldown). To invert the driver phase,drive TXP high or connect it to V CC . To invert the receiver phase, drive RXP high or connect it to V CC . Note that the receiver threshold is positive when RXP is high.The MAX13089E can operate in full- or half-duplex mode. Drive H/F low, leave it unconnected (internal pulldown), or connect it to GND for full-duplex opera-tion. Drive H/F high for half-duplex operation. In full-duplex mode, the pin configuration of the driver and receiver is the same as that of a MAX13080E. In half-duplex mode, the receiver inputs are internally connect-ed to the driver outputs through a resistor-divider. This effectively changes the function of the device’s outputs.Y becomes the noninverting driver output and receiver input, Z becomes the inverting driver output and receiver input. In half-duplex mode, A and B are still connected to ground through an internal resistor-divider but they are not internally connected to the receiver.±15kV ESD ProtectionAs 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 of the MAX13080E family of devices have extra protection against static electricity. Maxim’s engineers have devel-oped state-of-the-art structures to protect these pins against ESD of ±15kV without damage. The ESD struc-tures withstand high ESD in all states: normal operation,shutdown, and powered down. After an ESD event, the MAX13080E–MAX13089E keep working without latchup or damage.ESD protection can be tested in various ways. The transmitter outputs and receiver inputs of the MAX13080E–MAX13089E are characterized for protec-tion to the following limits:•±15kV using the Human Body Model•±6kV using the Contact Discharge method specified in IEC 61000-4-2ESD Test ConditionsESD performance depends on a variety of conditions.Contact Maxim for a reliability report that documents test setup, test methodology, and test results.Human Body ModelFigure 10a shows the Human Body Model, and Figure 10b 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 interest,which is then discharged into the test device through a 1.5k Ωresistor.IEC 61000-4-2The IEC 61000-4-2 standard covers ESD testing and performance of finished equipment. However, it does not specifically refer to integrated circuits. The MAX13080E family of devices helps you design equip-ment to meet IEC 61000-4-2, without the need for addi-tional ESD-protection components.+5.0V , ±15kV ESD-Protected, Fail-Safe, Hot-Swap, RS-485/RS-422 TransceiversThe major difference between tests done using the Human Body Model and IEC 61000-4-2 is higher peak current in IEC 61000-4-2 because series resistance is lower in the IEC 61000-4-2 model. Hence, the ESD with-stand voltage measured to IEC 61000-4-2 is generally lower than that measured using the Human Body Model. Figure 10c shows the IEC 61000-4-2 model, and Figure 10d shows the current waveform for IEC 61000-4-2 ESD Contact Discharge test.Machine Model The machine model for ESD tests all pins using a 200pF storage capacitor and zero discharge resis-tance. The objective is to emulate the stress caused when I/O pins are contacted by handling equipment during test and assembly. Of course, all pins require this protection, not just RS-485 inputs and outputs.Applications Information256 Transceivers on the BusThe standard RS-485 receiver input impedance is 12kΩ(1-unit load), and the standard driver can drive up to 32-unit loads. The MAX13080E family of transceivers has a1/8-unit load receiver input impedance (96kΩ), allowingup to 256 transceivers to be connected in parallel on one communication line. Any combination of these devices,as well as other RS-485 transceivers with a total of 32-unit loads or fewer, can be connected to the line.Reduced EMI and ReflectionsThe MAX13080E/MAX13081E/MAX13082E feature reduced slew-rate drivers that minimize EMI and reduce reflections caused by improperly terminated cables, allowing error-free data transmission up to250kbps. The MAX13083E/MAX13084E/MAX13085Eoffer higher driver output slew-rate limits, allowing transmit speeds up to 500kbps. The MAX13089E withSRL = V CC or unconnected are slew-rate limited. WithSRL unconnected, the MAX13089E error-free data transmission is up to 250kbps. With SRL connected toV CC,the data transmit speeds up to 500kbps. MAX13080E–MAX13089E+5.0V, ±15kV ESD-Protected, Fail-Safe, Hot-Swap, RS-485/RS-422 TransceiversM A X 13080E –M A X 13089ELow-Power Shutdown Mode (Except MAX13081E/MAX13084E/MAX13087E)Low-power shutdown mode is initiated by bringing both RE high and DE low. In shutdown, the devices typically draw only 2.8µA of supply current.RE and DE can be driven simultaneously; the devices 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 700ns, the devices are guaranteed to enter shutdown.Enable times t ZH and t ZL (see the Switching Characteristics section) assume the devices were not in a low-power shutdown state. Enable times t ZH(SHDN)and t ZL(SHDN)assume the devices were in shutdown state. It takes drivers and receivers longer to become enabled from low-power shutdown mode (t ZH(SHDN), t ZL(SHDN))than from driver/receiver-disable mode (t ZH , t ZL ).Driver Output ProtectionTwo mechanisms prevent excessive output current and power dissipation caused by faults or by bus contention.The first, a foldback current limit on the output stage,provides immediate protection against short circuits over the whole common-mode voltage range (see the Typical Operating Characteristics ). The second, a thermal-shut-down circuit, forces the driver outputs into a high-imped-ance state if the die temperature exceeds +175°C (typ).Line LengthThe RS-485/RS-422 standard covers line lengths up to 4000ft. F or line lengths greater than 4000ft, use the repeater application shown in Figure 11.Typical ApplicationsThe MAX13082E/MAX13085E/MAX13088E/MAX13089E transceivers are designed for bidirectional data commu-nications on multipoint bus transmission lines. F igures 12 and 13 show typical network applications circuits. To minimize reflections, terminate the line at both ends in its characteristic impedance, and keep stub lengths off the main line as short as possible. The slew-rate-lim-ited MAX13082E/MAX13085E and the two modes of the MAX13089E are more tolerant of imperfect termination.Chip InformationTRANSISTOR COUNT: 1228PROCESS: BiCMOS+5.0V , ±15kV ESD-Protected, Fail-Safe, Hot-Swap, RS-485/RS-422 TransceiversFigure 11.

_______________General DescriptionThe MAX753/MAX754 drive cold-cathode fluorescent lamps (CCFLs) and provide the LCD backplane bias (contrast) power for color or monochrome LCD panels.These ICs are designed specifically for backlit note-book-computer applications.Both the backplane bias and the CCFL supply can be shut down independently. When both sections are shut down, supply current drops to 25µA. The LCD contrast and CCFL brightness can be adjusted by clocking sep-arate digital inputs or using external potentiometers.LCD contrast and backlight brightness settings are pre-served in their respective counters while in shutdown.On power-up, the LCD contrast counter and CCFL brightness counter are set to one-half scale.The ICs are powered from a regulated 5V supply. The magnetics are connected directly to the battery, for maximum power efficiency.The CCFL driver uses a Royer-type resonant architec-ture. It can provide from 100mW to 6W of power to one or two tubes. The MAX753 provides a negative LCD bias voltage; the MAX754 provides a positive LCD bias voltage.________________________ApplicationsNotebook Computers Palmtop Computers Pen-Based Data Systems Personal Digital Assistants Portable Data-Collection Terminals____________________________Features♦Drives Backplane and Backlight ♦4V to 30V Battery Voltage Range ♦Low 500µA Supply Current♦Digital or Potentiometer Control of CCFL Brightness and LCD Bias Voltage ♦Negative LCD Contrast (MAX753)♦Positive LCD Contrast (MAX754)♦Independent Shutdown of Backlight and Backplane Sections ♦25µA Shutdown Supply Current______________Ordering Information* Contact factory for dice specifications.MAX753/MAX754CCFL Backlight and LCD Contrast Controllers________________________________________________________________Maxim Integrated Products1__________________Pin Configuration19-0197; Rev 1; 1/95For pricing, delivery, and ordering information, please contact Maxim Direct at 1-888-629-4642,or visit Maxim’s website at .M A X 753/M A X 754CCFL Backlight andLCD Contrast Controllers 2_______________________________________________________________________________________ABSOLUTE MAXIMUM RATINGSELECTRICAL CHARACTERISTICS(V DD = 5V, BATT = 15V, CON = LON = 5V, LX = G ND = PG ND = 0V, I REF = 0mA, all digital input levels are 0V or 5V, T A = T MIN to T MAX , unless otherwise noted.)Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device.

These lamps commonly provide backlighting for LCD panels in portable computers.Drive Requirements for CCFL TubesCCFL backlights require a high-voltage, adjustable AC power source. The MAX753/MAX754 generate this AC waveform with a self-oscillating, current-fed, parallel resonant circuit, also known as a Royer-type oscillator. Figure 1 shows one such circuit. The Royer oscillator is comprised of T1, C9, the load at the secondary, Q4,and Q5. The circuit self-oscillates at a frequency deter-mined by the effective primary inductance and capaci-tance. Q4 and Q5 are self-driven by the extra winding.The current source feeding the Royer oscillator is com-prised of L1, D5, and the MAX758A. When current from the current source increases, so does the lamp current.The lamp current is half-wave rectified by D7A andD7B, and forms a voltage across resistor R8. The MAX753’s error amplifier compares the average of this voltage to the output of its internal DAC. Adjusting the DAC output from zero scale to full scale (digital control)causes the error amplifier to vary the tube current from a minimum to a maximum. The DAC’s transfer function is shown in Figure 2.On power-up or after a reset, the counter sets the DAC output to mid scale. Each rising edge of CADJ (with CON high) decrements the DAC output. When decre-mented beyond full scale, the counter rolls over and sets the DAC to the maximum value. In this way, a sin-gle pulse applied to CADJ decreases the DAC set-point by one step, and 31 pulses increase the set-point by one step.The error amplifier’s output voltage controls the peak current output of the MAX758A. The peak switch cur-rent is therefore controlled by the output of the error amplifier. The lower the error amplifier’s output, the lower the peak current. Since the current through the current source is related to the current through the tube, the lower the error amplifier’s output, the lower the tube current.MAX753/MAX754CCFL Backlight and LCD Contrast Controllers_______________________________________________________________________________________5Figure 1. CCFL and Positive LCD Power SupplyM A X 753/M A X 754CCFL Backlight andLCD Contrast Controllers 6_______________________________________________________________________________________In Figure 1, the MAX758A, L1, and D5 form a voltage-controlled switch-mode current source. The current out of L1 is proportional to the voltage applied to the SS pin. The MAX758A contains a current-mode pulse-width-modulating buck regulator that switches at 170kHz. The voltage on the SS pin sets the switch cur-rent limit and thus sets the current out of L1.CCFL Current-Regulation LoopFigure 3 shows a block diagram of the regulation loop,which maintains a fixed CCFL average lamp current despite changes in input voltage and lamp impedance.This loop regulates the average value of the half-wave rectified lamp current. The root mean square lamp cur-rent is related to, but not equal to, the average lamp current. Assuming a sinusoidal lamp current, select R8where V REF = 1.25V and I LAMP,RMS is the desired full-scale root mean square lamp current.Figure 2. CCFT DAC Transfer FunctionFigure 3. CCFL Tube Current-Regulation LoopThe minimum operating input voltage is determined by the transformer turns ratio (n), the lamp operating volt-age (V LAMP ), and the ballast capactor (C10). Using a simple model of the CCFL (see Figure 4) we can calcu-late what the T1 center-tap voltage will be at maximum lamp current. The voltage on the CCFL is in phase with the current through it. Let us define I LAMP (t) =LAMP,RMS cos(ωt) and V LAMP (t) = √LAMP,RMS cos(ωt); then the peak voltage at the center tap will bewhere,n is the secondary-to-primary turns ratio of T1, and ω is the frequency of Royer oscillation in radians per sec-ond. The voltage on the center tap of T1 is a full-wave rectified sine wave (see Figure 5). The average voltage at V TAP must equal the average voltage at the LX node of the MAX758A, since there cannot be any DC voltage on inductor L1; thus the minimum operating voltage must be greater than the average voltage at V TAP .LCD Bias GeneratorsThe MAX753/MAX754’s LCD bias generators provide adjustable output voltages for powering LCD displays.The MAX753’s LCD converter generates a negative output, while the MAX754’s generates a positive output.The MAX753/MAX754 employ a constant-peak-currentpulse-frequency-modulation (PFM) switching regulator.The MAX753 adds a simple diode-capacitor voltage inverter to the switching regulator.Constant-Current PFM Control SchemeThe LCD bias generators in these devices use a con-stant-peak-current PFM control scheme. Figure 6, which shows the MAX754’s boost switching regulator, illus-trates this control method. When Q3 closes (Q3 “on”) a voltage equal to BATT is applied to the inductor, caus-ing current to flow from the battery, through the inductor and switch, and to ground. This current ramps up linear-ly, storing energy in the inductor’s magnetic field. When Q3 opens, the inductor voltage reverses, and current flows from the battery, through the inductor and diode,and into the output capacitor. The devices regulate the output voltage by varying how frequently the switch is opened and closed.The MAX753/MAX754 not only regulate the output volt-age, but also maintain a constant peak inductor cur-rent, regardless of the battery voltage. The ICs vary the switch on-time to produce the constant peak current,and vary its off-time to ensure that the inductor current reaches zero at the end of each cycle.The internal circuitry senses both the output voltage and the voltage at the LX node, and turns on the MOS-FET only if: 1) The output voltage is out of regulation,and 2) the voltage at LX is less than the battery voltage.The first condition keeps the output in regulation, and the second ensures that the inductor current always resets to zero (i.e., the part always operates in discon-tinuous-conduction mode).MAX753/MAX754CCFL Backlight and LCD Contrast Controllers_______________________________________________________________________________________7Figure 4.

MAX754 Positive LCD-Bias GeneratorTable 1. CCFL Circuit Component DescriptionsITEMDESCRIPTIONC5Integrating Capacitor. 1 / (C5 x R18) sets the dominant pole for the feedback loop, which regulates the lamp current. Set the dominant pole at least two decades below the Royer frequency to eliminate the AC compo-nent of the voltage on R8. For example, if your Royer is oscillating at 50kHz = 314159rad/s, you should set 1 / (C5 x R18) ≤3142rad/s.R18Integrating Resistor. The output source-current capability of the CC pin (50µA) limits how small R18 can be.Do not make R18 smaller than 70k Ω, otherwise CC will not be able to servo CFB to the DAC voltage (i.e., the integrator will not be able to integrate) and the loop will not be able to regulate.R8R8 converts the half-wave rectified lamp current into a voltage. The average voltage on R8 is not equal to the root mean square voltage on R8. The accuracy of R8 is important since it, along with the MAX754 reference,sets the full-scale lamp current. Use a ±1%-accurate resistor.D7A, D7BD7A and D7B half-wave rectify the CCFL lamp current. Half-wave rectification of the lamp current and then averaging is a simple way to perform AC-to-DC conversion. D7A and D7B’s forward voltage drop and speed are unimportant; they do not need to pass currents larger than about 10mA, and their reverse breakdown voltage can be as low as 10V.CCFLThe circuit of Figure 1, with the components shown in the bill of materials (Table 4), will drive a 500V RMS oper-ating cold-cathode fluorescent lamp at 6W of power with a +12V input voltage. The lower the input voltage,the less power the circuit can deliver.MAX753/MAX754CCFL Backlight and LCD Contrast Controllers_______________________________________________________________________________________9Table 1.

General DescriptionThe MAX481, MAX483, MAX485, MAX487–MAX491, andMAX1487 are low-power transceivers for RS-485 and RS-422 communication. Each part contains one driver and onereceiver. The MAX483, MAX487, MAX488, and MAX489feature reduced slew-rate drivers that minimize E MI andreduce 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 totransmit up to 2.5Mbps.These transceivers draw between 120µA and 500µA ofsupply current when unloaded or fully loaded with disableddrivers. Additionally, the MAX481, MAX483, and MAX487have a low-current shutdown mode in which they consumeonly 0.1µA. All parts operate from a single 5V supply.Drivers are short-circuit current limited and are protectedagainst excessive power dissipation by thermal shutdowncircuitry that places the driver outputs into a high-imped-ance state. The receiver input has a fail-safe feature thatguarantees a logic-high output if the input is open circuit.The MAX487 and MAX1487 feature quarter-unit-loadreceiver input impedance, allowing up to 128 MAX487/MAX1487 transceivers on the bus. Full-duplex communi-cations are obtained using the MAX488–MAX491, whilethe MAX481, MAX483, MAX485, MAX487, and MAX1487are designed for half-duplex applications.________________________Applications Low-Power RS-485 Transceivers Low-Power RS-422 Transceivers Level Translators Transceivers for EMI-Sensitive Applications Industrial-Control Local Area Networks__Next Generation Device Features o For Fault-Tolerant Applications MAX3430: ±80V Fault-Protected, Fail-Safe, 1/4Unit Load, +3.3V, RS-485 Transceiver MAX3440E–MAX3444E: ±15kV ESD-Protected,±60V Fault-Protected, 10Mbps, Fail-Safe, RS-485/J1708 Transceivers o For Space-Constrained Applications MAX3460–MAX3464: +5V, Fail-Safe, 20Mbps,Profibus RS-485/RS-422 Transceivers MAX3362: +3.3V, High-Speed, RS-485/RS-422Transceiver in a SOT23 Package MAX3280E–MAX3284E: ±15kV ESD-Protected,52Mbps, +3V to +5.5V, SOT23, RS-485/RS-422,True Fail-Safe Receivers MAX3293/MAX3294/MAX3295: 20Mbps, +3.3V,SOT23, RS-485/RS-422 Transmitters o For Multiple Transceiver Applications MAX3030E–MAX3033E: ±15kV ESD-Protected,+3.3V, Quad RS-422 Transmitters o For Fail-Safe Applications MAX3080–MAX3089: Fail-Safe, High-Speed (10Mbps), Slew-Rate-Limited RS-485/RS-422Transceiverso For Low-Voltage ApplicationsMAX3483E/MAX3485E/MAX3486E/MAX3488E/MAX3490E/MAX3491E: +3.3V Powered, ±15kVESD-Protected, 12Mbps, Slew-Rate-Limited,True RS-485/RS-422 Transceivers For pricing, delivery, and ordering information, please contact Maxim Direct at1-888-629-4642, or visit Maxim Integrated’s website at .______________________________________________________________Selection Table19-0122; Rev 10; 9/14PARTNUMBERHALF/FULL DUPLEX DATA RATE (Mbps) SLEW-RATE LIMITED LOW-POWER SHUTDOWN RECEIVER/DRIVER ENABLE QUIESCENT CURRENT (μA) NUMBER OF RECEIVERS ON BUS PIN COUNT MAX481Half 2.5No Yes Yes 300328MAX483Half 0.25Yes Yes Yes 120328MAX485Half 2.5No No Yes 300328MAX487Half 0.25Yes Yes Yes 1201288MAX488Full 0.25Yes No No 120328MAX489Full 0.25Yes No Yes 1203214MAX490Full 2.5No No No 300328MAX491Full 2.5No No Yes 3003214MAX1487 Half 2.5No No Yes 2301288Ordering Information appears at end of data sheet.找电子元器件上宇航军工MAX481/MAX483/MAX485/MAX487–MAX491/MAX1487Low-Power, Slew-Rate-LimitedRS-485/RS-422 TransceiversPackage Information For the latest package outline information and land patterns, go to .

On-resistance is matched between switches to 0.5Ωmax and is flat (0.5Ωmax) over the specified signal range. Each switch can handle Rail-to-Rail ®analog signals. The off-leakage cur-rent is only 2.5nA max at +85°C. These analog switches are ideal in low-distortion applications and are the pre-ferred solution over mechanical relays in automatic test equipment or in applications where current switching is required. These switches have low power requirements,require less board space, and are more reliable than mechanical relays.The MAX4604 has four normally closed (NC) switches,the MAX4605 has four normally open (NO) switches,and the MAX4606 has two NC and two NO switches.These switches operate from a single supply of +4.5V to +36V or from dual supplies of ±4.5V to ±20V. All dig-ital inputs have +0.8V and +2.4V logic thresholds,ensuring TTL/CMOS logic compatibility when using ±15V supplies or a single +12V supply.ApplicationsReed Relay Replacement PBX, PABX Systems Test EquipmentAudio-Signal Routing Communication SystemsAvionicsFeatureso Low On-Resistance (5Ωmax)o Guaranteed R ON Match Between Channels (0.5Ωmax)o Guaranteed R ON Flatness over Specified Signal Range (0.5Ωmax)o Rail-to-Rail Signal Handlingo Guaranteed ESD Protection > 2000V per Method 3015.7o Single-Supply Operation: +4.5V to +36V Dual-Supply Operation: ±4.5V to ±20V o TTL/CMOS-Compatible Control InputsMAX4604/MAX4605/MAX46065Ω, Quad, SPST, CMOS Analog Switches________________________________________________________________Maxim Integrated Products1Pin Configurations/Functional Diagrams/Truth Tables19-1393; Rev 1; 8/99Ordering Information continued at end of data sheet.Ordering InformationRail-to-Rail is a registered trademark of Nippon Motorola, Ltd.M A X 4604/M A X 4605/M A X 46065Ω, Quad, SPST, CMOS Analog Switches 2_______________________________________________________________________________________ABSOLUTE MAXIMUM RATINGSNote 1:Signals on NC_, NO_, COM_, or IN_ exceeding V+ or V- are clamped by internal diodes.

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, or COM. If power-supply sequencing is not possible, add two small signal diodes (D1, D2) in series with 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 44V. These protection diodes are not recommended when using a single supply.Off-Isolation at High FrequenciesIn 50Ωsystems, the high-frequency on-response of these parts extends from DC to above 100MHz with a typical loss of -2dB. When the switch is turned off, how-ever, it behaves like a capacitor, and off isolation decreases with increasing frequency. (Above 300MHz,the switch actually passes more signal turned off than turned on.) This effect is more pronounced with higher source and load impedances.Above 5MHz, circuit board layout becomes critical, and it becomes difficult to characterize the response of theswitch independent of the circuit. The graphs shown in the Typical Operating Characteristics were taken using a 50Ωsource and load connected with BNC connec-tors to a circuit board deemed “average;” that is,designed with isolation in mind, but not using strip-line or other special RF circuit techniques. For critical appli-cations above 5MHz, use the MAX440, MAX441, and MAX442, which are fully characterized up to 160MHz.Figure 1. Overvoltage Protection Using External Blocking DiodesFigure 2.

The MAX3080–MAX3089 high-speed transceivers for RS-485/RS-422 communication contain one driver and one receiver. These devices feature fail-safe circuitry, which guarantees a logic-high receiver output when the receiver inputs are open or shorted. This means that the receiver output will be a logic high if all transmitters on a terminated bus are disabled (high impedance). The MAX3080/MAX3081/MAX3082 feature reduced slew-rate drivers that minimize EMI and reduce reflections caused by improperly terminated cables, allowing error-free data transmission up to 115kbps. The MAX3083/MAX3084/MAX3085 offer higher driver output slew-rate limits, allowing transmit speeds up to 500kbps. The MAX3086/MAX3087/MAX3088’s driver slew rates are not limited, making transmit speeds up to 10Mbps possible. The MAX3089’s slew rate is selectable between 115kbps, 500kbps, and 10Mbps by driving a selector pin with a single three-state driver.

5Ω, Quad, SPST, CMOS Analog Switches
General Description
The MAX4604/MAX4605/MAX4606 quad analog switches feature 5 Ω max on-resistance. On-resistance is matched between switches to 0.5Ω max and is flat (0.5Ω max) over the specified signal range. Each switch can handle Rail-to-Rail® analog signals. The off-leakage current is only 2.5nA max at +85°C. These analog switches are ideal in low-distortion applications and are the preferred solution over mechanical relays in automatic test equipment or in applications where current switching is required. These switches have low power requirements, require less board space, and are more reliable than mechanical relays. The MAX4604 has four normally closed (NC) switches, the MAX4605 has four normally open (NO) switches, and the MAX4606 has two NC and two NO switches. These switches operate from a single supply of +4.5V to +36V or from dual supplies of ±4.5V to ±20V. All digital inputs have +0.8V and +2.4V logic thresholds, ensuring TTL/CMOS logic compatibility when using ±15V supplies or a single +12V supply. o Low On-Resistance (5Ω max) o Guaranteed RON Match Between Channels (0.5Ω max) o Guaranteed RON Flatness over Specified Signal Range (0.5Ω max) o Rail-to-Rail Signal Handling o Guaranteed ESD Protection > 2000V per Method 3015.7 o Single-Supply Operation: +4.5V to +36V Dual-Supply Operation: ±4.5V to ±20V o TTL/CMOS-Compatible Control Inputs
