CRS001 is a robust half-duplex RS-485
transceiver for industrial applications. The bus
pins are immune to high levels of ESD events.
The device operates from a single 5V supply. The
wide common-mode voltage range and low input
leakage on bus pins make suitable for multi-point
applications over long cable runs.
CRS001 is available in industrial standard 8-pin
SOIC package for drop-in compatibility.
