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 SP202E family (including SP232E, SP233E, SP310E, and SP312E) are high‑performance RS‑232 line driver and receiver pairs that meet EIA RS‑232 and ITU V.28 specifications. They operate from a single +5 V supply, provide up to 120 kbps data rate under load, and feature a BiCMOS design for low power consumption while maintaining ruggedness for commercial applications.
Key features include enhanced ESD tolerance (≥+15 kV for both Human Body Model and IEC 1000‑4‑2 air discharge), internal charge‑pump voltage converters, optional shutdown and wake‑up functions, and a variety of package options such as 18‑pin PDIP, 16‑pin WSOIC, and 20‑pin SSOP. The datasheet also provides detailed electrical characteristics, pinouts, and ordering information.
