The device 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 from a single 5-V supply. The devices operate at data signaling rates up to 120 kbit/s and a maximum of 30-V/μs driver output slew rate.
