The SN65C3232E and SN75C3232E consist 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). These devices 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. The devices

operate at data signaling rates up to 1 Mbit/s and a driver output slew rate of 14 V/

µs to 150 V/µs.
