Overview
The TRS3232EIPWRG4 is a multichannel 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 two line drivers and two line receivers, along with a dual charge-pump circuit that enables operation from a single 3V to 5.5V supply. The device is notable for its robust ESD protection, supporting up to ±15kV IEC ESD protection pin to pin, including serial-port connection pins and ground.
