DESCRIPTION/

ORDERING INFORMATION

The TRSF3223E 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 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 TRSF3223E operates

at typical data signaling rates up to 1000 kbit/s.
