The SP202E, SP232E and SP233E devices are a family of
line driver and receiver pairs that meets the specifications of
RS-232 and V.28 serial protocols. The devices are pin-to-pin
compatible with MaxLinear’s SP232A and SP233A devices
as well as popular industry standard pinouts. The ESD
tolerance has been improved on these devices to over ±15kV
for Human Body Model. This series offers a 120kbps data
rate under load, small ceramic type 0.1µF charge pump
capacitors and overall ruggedness for commercial
applications. Features include MaxLinear’s BiCMOS design
which allows low power operation without sacrificing
performance. The series is available in lead free packages
and includes commercial and industrial temperature ranges.
