The MAX3221CUE+ with RS-232 Interface IC from Analog Devices is an integrated circuit designed for serial data communication. It operates from true +3V to +5.5V, offering a maximum supply-current of 1 uA for both transmission and reception. The device features AutoShutdown functionality which helps to reduce power consumption by shutting down the transceivers when the RS-232 connection is inactive. The integrated transceivers are compliant with RS-232 signalling, allowing the device to be used in many applications including Point-of-Sale terminals, cash registers, TVs, STBs, terminals, modems, and industrial control equipment.
