DESCRIPTION
The TRS3232E device consists of two line drivers, two line receivers, and a dual charge-pump circuit with
±15-kV 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 3-V to 5.5-V supply. The devices operate at data signaling rates up to 250 kbit/s and a maximum of
30-V/µs driver output slew rate.
