+5.0V, ±15kV ESD-Protected, Fail-Safe,
Hot-Swap, RS-485/RS-422 Transceiver
General Description
The MAX13085E +5.0V, ±15kV ESD-protected, RS-485/
RS-422 transceiver features one driver and one receiver.
The device includes 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 MAX13085E includes a hot-swap
capability to eliminate false transitions on the bus during
power-up or hot insertion.
The MAX13085E features reduced slew-rate drivers
that minimize EMI and reduce reflections caused by
improperly terminated cables, allowing error-free data
transmission up to 500kbps.
The MAX13085E is ideal for half-duplex communications
and it draws 1.2mA of supply current when unloaded
or when fully loaded with the drivers disabled. The
MAX13085E has a 1/8-unit load receiver input imped-
ance, allowing up to 256 transceivers on the bus.
The MAX13085E is available in an 8-pin SO and PDIP
packages.
