3 Description
The MAX3222 consists of two line drivers, two line receivers, and a dual charge-pump circuit with ±15-k V 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 munication 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...
