MAX22502E
100Mbps Full-Duplex RS-485/RS-422
Transceiver for Long Cables
General Description
The MAX22502E full-duplex, ESD-protected, RS-485/
RS-422 transceiver is optimized for high-speed (up to
100Mbps) communication over long cables.This transceiver
features larger receiver hysteresis for high noise rejection
and improved signal integrity. Integrated preemphasis
circuitry extends the distance, and increases the data rate,
of reliable communication by reducing inter-symbol
interference (ISI) caused by long cables when supplied with
5V. Integrated hot-swap protection and a fail-safe receiver
ensure a logic-high on the receiver output when input signals
are shorted or open for longer than 10μs (typ).
The MAX22502E is available in a 12-pin TDFN-EP (3mm
x 3mm) package and operates over the -40°C to +125°C
ambient temperature range.
