The MAX3232 device 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 devices operate at data signaling rates up to 250 kbit/s and a maximum of 30-V/s driver output slew rate. The MAX3232C is characterized for operation from 0C to 70C. The MAX3232I is characterized for operation from 40C to 85C.
