The TRSF3232E consists 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). This device 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 TRSF3232E operates

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

μs to 150 V/μs.
