Product Summary

The MAX3223CPWR is a 3V to 5.5V multi-channel RS-232 line driver/receiver. The MAX3223CPWR 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 MAX3223CPWR 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 MAX3223CPWR operates at data signaling rates up to 250kbit/s and a maximum of 30-V/μs driver output slew rate.
