DESCRIPTION/ORDERING INFORMATION
The TRSF3232 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 TRSF3232 operates at typical
data signaling rates up to 1 Mbit/s and a driver output slew rate of 24 V/μs to 150 V/μs.
