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.
