General Description

The SN65C3222E and SN75C3222E consist of two line drivers, two line receivers, and a dual chargepump circuit with ±15-kV ESD protection pin to pin (serial-port connection pins, including GND).

The devices meet the requirements of TIA/EIA-232F and provide 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 3-V to 5.5-V supply.
