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–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 256

transceivers 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. The devices operate over the com-

mercial, extended, and automotive temperature ranges.
