3 Description

The TRSF3232E consists of two line drivers, two line

receivers, and a dual charge-pump circuit with ±15kV

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 3V to 5.5V supply. The

TRSF3232E operates at data signaling rates up to

1Mbit/s and a driver output slew rate of 14V/μs to

150V/μs.
