DESCRIPTION…
The SP202E/232E/233E/310E/312E devices are a family of line driver and receiver pairs that
meet the specifications of RS-232 and V.28 serial protocols with enhanced ESD performance.
The ESD tolerance has been improved on these devices to over ±15KV for both Human Body
Model and IEC1000-4-2 Air Discharge Method. These devices are pin-to-pin compatible with
Sipex's SP232A/233A/310A/312A devices as well as popular industry standards. As with the
initial versions, the SP202E/232E/233E/310E/312E 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 and ceramic DIP and SOIC packages
operating over the commercial, industrial and military temperature ranges.
