description/ordering informationThe MAX3222 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 therequirements of TIA/EIA-232-F and provides the electrical interface between an asynchronous communicationcontroller and the serial-port connector. The charge pump and four small external capacitors allow operationfrom a single 3-V to 5.5-V supply. The device operates at data signaling rates up to 250 kbit/s and a maximumof 30-V/μs driver output slew rate.
