Overview
The MAX3232CDWRG4 is a 3-V to 5.5-V multichannel RS-232 line driver and receiver produced by Texas Instruments. This integrated circuit (IC) is designed to provide the electrical interface between an asynchronous communication controller and the serial-port connector. It consists of two line drivers, two line receivers, and a dual charge-pump circuit, which allows operation from a single 3-V to 5.5-V supply. The device meets the requirements of TIA/EIA-232-F and offers ±15-kV ESD protection terminal to terminal, including GND. It is suitable for various applications requiring reliable data transmission over long distances.
