INFORMATION
The SN65C3223E and SN75C3223E consist of two
line drivers, two line receivers, and a dual
charge-pump circuit with В±15-kV ESD protection pin
to pin (serial-port connection pins, including GND).
These devices meet the requirements of
TIA/EIA-232-F and provide 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 devices operate at
typical data signaling rates up to 1000 kbit/s. 19
