DESCRIPTION/ORDERING INFORMATION
The MAX3223 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). The 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 device operates at typical data signaling rates up to 250 kbit/s and a maximum of 30-V/ms
driver output slew rate.
