TRS3222E Overview
The TRS3222E consists of two line drivers, two line receivers, and a dual charge-pump circuit with ±15-kV ESD protection pin to pin (serial-port connection pins, including GND). The device meets the requirements of TIA/EIA-232F and provides the electrical interface between an asynchronous munication controller and the serial-port connector. The charge pump and four small external capacitors allow operation from a...
