Overview
The MAX3232IPWG4, produced by Texas Instruments, is a 3-V to 5.5-V multichannel RS-232 line driver and receiver. 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 3-V to 5.5-V supply, along with four small external capacitors. The MAX3232IPWG4 includes two line drivers and two line receivers, offering robust ESD protection of ±15 kV using the human-body model (HBM) and ±8 kV and ±15 kV for IEC61000-4-2 contact and air-gap discharges, respectively.
