TRSF3222E Overview
The TRSF3222E 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 TRSF3222E meets the requirements of TIA/ EIA-232-F 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...
