Overview
The TRS202EIPWR is a 5-V dual RS-232 line driver and receiver produced by Texas Instruments. This device is designed to provide a reliable and robust interface between an asynchronous communication controller and a serial-port connector. It includes two line drivers, two line receivers, and a dual charge-pump circuit, enabling operation from a single 5-V supply with the aid of four small external capacitors. The TRS202EIPWR meets or exceeds the requirements of TIA/EIA-232-F and ITU v.28 standards, making it suitable for a variety of applications requiring RS-232 communication.
