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 data signaling rates up to 250 kbit/s and a maximum of 30-V/µs
driver output slew rate.
