Overview
The SN65C3232EDBRG4 is a robust, dual-channel RS-232 transceiver manufactured by Texas Instruments. It is designed to meet the stringent requirements of the EIA/TIA-232-F standards and provides enhanced electrostatic discharge (ESD) protection. This device consists of two line drivers, two line receivers, and a dual charge-pump circuit with ±15-kV ESD protection between serial-port connection terminals and GND. It operates as the electrical interface between an asynchronous communication controller and the serial-port connector, allowing operation from a single 3-V to 5.5-V supply.
