DESCRIPTION

SELECTION TABLE

The SP232A/233A/310A/312A devices are a family of line driver and receiver pairs that meet the

specifications of RS-232 and V.28 serial protocols. These devices are pin-to-pin compatible with

popular industry standards. As with the initial versions, the SP232A/233A/310A/312A devices

feature at least 120Kbps data rate under load, 0.1µF charge pump capacitors, and overall

ruggedness for commercial applications. This family also features Sipex's BiCMOS design

allowing low power operation without sacrificing performance. The series is available in plastic

DIP and SOIC packages operating over the commercial and industrial temperature ranges.
