General Description

The 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 family 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 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/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 family 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 256 trans-

ceivers on the bus.

The MAX13080E/MAX13083E/MAX13086E/MAX13089E

are available in 14-pin PDIP and 14-pin SO packages. The

MAX13081E/MAX13082E/MAX13084E/MAX13087E/

MAX13088E are available in 8-pin PDIP and 8-pin SO

packages. The devices operate over the commercial,

extended, and automotive temperature ranges.
