Overview
The MAX3232IDBG4 is a multichannel RS-232 line driver/receiver integrated circuit produced by Texas Instruments. This device is designed to provide an electrical interface between an asynchronous communication controller and a serial-port connector, adhering to the TIA/EIA-232-F and ITU V.28 standards. It operates with a single 3-V to 5.5-V supply voltage and includes a dual charge-pump circuit that requires four external capacitors for operation. The MAX3232IDBG4 features ±15-kV ESD protection on all serial-port connection terminals, including ground, making it robust against electrical surges.
