The TRS3232E device consists of two line drivers, two-line receivers, and a dual charge-pump circuit with ±15kV IEC ESD protection pin to pin (serial-port connection pins, 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. The charge pump and four small external capacitors allow operation from a single 3V to 5.5V supply. The devices operate at data signaling rates up to 250kbps and a maximum of 30V/µs driver output slew rate.
