The MAX13080E-MAX13089E +5.0V, ±15kV ESD-protected,
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 communications.
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 commercial,
extended, and automotive temperature ranges.
