Overview
The TRS202EIPWRG4 is a 5-V dual RS-232 line driver and receiver integrated circuit produced by Texas Instruments. This device is designed to provide the electrical interface between an asynchronous communication controller and the serial-port connector, adhering to the TIA/EIA-232-F and ITU v.28 standards. It features a dual charge-pump circuit that allows operation from a single 5-V supply, along with four small external capacitors. The TRS202EIPWRG4 is equipped with robust ESD protection, meeting IEC61000-4-2 (Level 4) standards, and supports data signaling rates up to 120 kbit/s.
