The MAX3232EIPWR is a low-power, low-noise, RS-232 interface IC designed to convert logic levels between a wide range of power supply voltages and the higher (3-5.5V) levels needed for RS-232 communication. This MultiCh line driver/receiver IC also features a slew rate of 75-V/µs, requiring only four 0.1µF external capacitors and operating from a single 3.0-5.5V DC power supply. In addition, this IC includes five protection features: ESD (electrostatic discharge) protection, short circuit protection, thermal shutdown, output overvoltage protection, and receiver input overvoltage protection.
