General Description
Features
The MAX13080E–MAX13089E +5.0V, ±15kV ESD-protect-ed, RS-485/RS-422 transceivers feature one driver and♦+5.0V Operation
one receiver. These devices include fail-safe circuitry,♦Extended ESD Protection for RS-485/RS-422 I/O Pins
guaranteeing a logic-high receiver output when receiver±15kV Human Body Modelinputs are open or shorted. The receiver outputs a logic-high if all transmitters on a terminated bus are disabled♦True Fail-Safe Receiver While Maintaining(high impedance). The MAX13080E–MAX13089E includeEIA/TIA-485 Compatibility a hot-swap capability to eliminate false transitions on the♦Hot-Swap Input Structures on DE and REbus during power-up or hot insertion.
The MAX13080E/MAX13081E/MAX13082E feature♦Enhanced Slew-Rate Limiting Facilitates Error-reduced slew-rate drivers that minimize EMI andFree Data Transmission
reduce reflections caused by improperly terminated(MAX13080E–MAX13085E/MAX13089E)cables, allowing error-free data transmission up to♦Low-Current Shutdown Mode (Except250kbps. The MAX13083E/MAX13084E/MAX13085EMAX13081E/MAX13084E/MAX13087E)also feature slew-rate-limited drivers but allow transmitspeeds up to 500kbps. The MAX13086E/MAX13087E/♦Pin-Selectable Full-/Half-Duplex OperationMAX13088E driver slew rates are not limited, making(MAX13089E)transmit speeds up to 16Mbps possible. TheMAX13089E slew rate is pin selectable for 250kbps,♦Phase Controls to Correct for Twisted-Pair500kbps, and 16Mbps.

MAX13081E/MAX13083E/MAX13084E/MAX13086E/MAX13087E are intended for full-duplex communica-tions. The MAX13089E is selectable for half-duplex orfull-duplex operation. It also features independentlyprogrammable receiver and transmitter output phasethrough separate pins.
Ordering Information
The MAX13080E–MAX13089E transceivers draw 1.2mAof supply current when unloaded or when fully loadedwith the drivers disabled. All devices have a 1/8-unitPARTTEMP RANGEPIN-PKGPACKAGECODEload receiver input impedance, allowing up to 256transceivers on the bus.

In half-duplex mode, A and B are still connected toground through an internal resistor-divider but they arenot internally connected to the receiver.
±15kV ESD Protection
As with all Maxim devices, ESD-protection structuresare incorporated on all pins to protect against electro-static discharges encountered during handling andassembly. The driver outputs and receiver inputs of theMAX13080E family of devices have extra protectionagainst static electricity. Maxim’s engineers have devel-oped state-of-the-art structures to protect these pinsagainst 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, theMAX13080E–MAX13089E keep working without latchupor damage.
ESD protection can be tested in various ways. Thetransmitter outputs and receiver inputs of theMAX13080E–MAX13089E are characterized for protec-tion to the following limits:
•±15kV using the Human Body Model
•±6kV using the Contact Discharge method specifiedin IEC 61000-4-2
ESD Test Conditions
ESD performance depends on a variety of conditions.Contact Maxim for a reliability report that documentstest setup, test methodology, and test results.
Human Body Model
Figure 10a shows the Human Body Model, and Figure10b shows the current waveform it generates when dis-charged into a low impedance. This model consists of a100pF capacitor charged to the ESD voltage of interest,which is then discharged into the test device through a1.5kΩresistor.
IEC 61000-4-2
The IEC 61000-4-2 standard covers ESD testing andperformance of finished equipment. However, it doesnot specifically refer to integrated circuits. TheMAX13080E family of devices helps you design equip-ment to meet IEC 61000-4-2, without the need for addi-tional ESD-protection components.
5kΩDE100µA500µAM1M2DE(HOT SWAP)Figure 9. Simplified Structure of the Driver Enable Pin (DE)MAX13089E Programming
The MAX13089E has several programmable operatingmodes. 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 athree-state driver: VCC, GND, or unconnected. For250kbps operation, set the three-state device in high-impedance mode or leave SRL unconnected. For500kbps operation, drive SRL high or connect it to VCC.For 16Mbps operation, drive SRL low or connect it toGND. SRL can be changed during operation withoutinterrupting data communications.
Occasionally, twisted-pair lines are connected backwardfrom normal orientation. The MAX13089E has two pinsthat invert the phase of the driver and the receiver to cor-rect this problem. For normal operation, drive TXP andRXP low, connect them to ground, or leave them uncon-nected (internal pulldown). To invert the driver phase,drive TXP high or connect it to VCC. To invert the receiverphase, drive RXP high or connect it to VCC. Note that thereceiver threshold is positive when RXP is high.
The MAX13089E can operate in full- or half-duplexmode. Drive H/Flow, leave it unconnected (internalpulldown), or connect it to GND for full-duplex opera-16

Low-power shutdown mode is initiated by bringing bothREhigh and DE low. In shutdown, the devices typicallydraw only 2.8µA of supply current.
REand DE can be driven simultaneously; the devicesare guaranteed not to enter shutdown if REis high andDE is low for less than 50ns. If the inputs are in thisstate for at least 700ns, the devices are guaranteed toenter shutdown.
Enable times tZHand tZL(see the SwitchingCharacteristics section) assume the devices were not ina low-power shutdown state. Enable times tZH(SHDN)andtZL(SHDN)assume the devices were in shutdown state. Ittakes drivers and receivers longer to become enabledfrom low-power shutdown mode (tZH(SHDN), tZL(SHDN))than from driver/receiver-disable mode (tZH, tZL).
Driver Output Protection
Two mechanisms prevent excessive output current andpower dissipation caused by faults or by bus contention.The first, a foldback current limit on the output stage,provides immediate protection against short circuits overthe whole common-mode voltage range (see the TypicalOperating 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 Length
The RS-485/RS-422 standard covers line lengths up to4000ft. For line lengths greater than 4000ft, use therepeater application shown in Figure 11.
Typical Applications
The MAX13082E/MAX13085E/MAX13088E/MAX13089Etransceivers are designed for bidirectional data commu-nications on multipoint bus transmission lines. Figures12 and 13 show typical network applications circuits. To minimize reflections, terminate the line at both endsin its characteristic impedance, and keep stub lengthsoff the main line as short as possible. The slew-rate-lim-ited MAX13082E/MAX13085E and the two modes of theMAX13089E are more tolerant of imperfect termination.
