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.
