DESCRIPTION
The SP202E, SP232E, SP233E, SP310E and SP312E devices are a family of line driver and re-
ceiver pairs that meets the specifications of RS-232 and V.28 serial protocols. The devices are pin-
to-pin compatible with Exar's SP232A, SP233A, SP310A and SP312A 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 offer a 120kbps data rate under load, small ceramic type 0.1μF
charge pump capacitors and overall ruggedness for comercial applications. Features include Exar's
BiCMOS design which allowing low power operation without sacrificing performance. The series is
available in lead free packages with commercial and industrial temperature ranges.
