Overview
The MAX3232EIPW is a multichannel RS-232 line driver and receiver produced by Texas Instruments. This device is designed to provide an electrical interface between an asynchronous communication controller and a serial-port connector. It operates with a supply voltage range of 3-V to 5.5-V and is compatible with TIA/EIA-232-F and ITU V.28 standards. The MAX3232EIPW features two line drivers and two line receivers, along with a dual charge-pump circuit that requires four small external capacitors for operation. It is notable for its high ESD protection, with ±15 kV HBM and ±15 kV IEC61000-4-2 protection for serial-port connection pins, including GND.
