The MAX3221 device consists of one line driver, one line receiver with dedicated enable pin, 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-232F 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.
