Transceivers for Long Cables
General Description
The MAX22500E/MAX22501E half-duplex ESD-protected
RS-485/RS-422 transceivers are optimized for high-
speed (up to 100Mbps) communication over long cables.
These transceivers feature integrated hot-swap protection
and a fail-safe receiver, ensuring a logic-high on the
receiver output when input signals are shorted or open for
longer than 10μs (typ).
The MAX22500E features integrated preemphasis circuitry
that extends the distance and increases the data rate of
reliable communication by reducing inter-symbol interference
(ISI) caused by long cables. The MAX22500E features a
flexible logic interface down to 1.6V.
The MAX22501E operates without preemphasis and is
powered from a 3V to 5.5V supply.
The MAX22500E is available in a 10-pin TDFN-EP package.
The MAX22501E is available in a 8-pin TDFN-EP package.
Both transceivers operate over the -40°C to +125°C ambient
temperature range.
