MAX3232 is a TTL to RS232 converter and is used in place of MAX232 in circuits which work on 3.3 volts.
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 signalling rates up to 250 kbit/s and a maximum of 30-V/µs driver output slew rate.
