TRS3232 - Texas Instruments

TRS3232 3-V to 5.5-V Multichannel RS-232 Line Driver/Receiver

The TRS3232 consists of two line drivers, two line receivers, and a dual charge-pump circuit with ±15-kV ESD protection terminal-to-terminal (serialport connection terminals, including GND). The device meets the requirements of TIA/EIA-232-F and provides the electrical interface between an asynchronous communication controller and the serial-port connector..
