The MAX3221EETE+T with RS-232 Interface IC by Analog Devices is a high performance, low power, ESD-protected transceiver for RS-232 applications. Featuring a shutdown mode that can reduce power supply current to 1 µA, this device performs full-duplex communication in both directions and is capable of data transfer rates up to 250 kbps. It also features an integrated voltage-translation circuit that operates from 3.0V to 5.5V and can withstand 15kV ESD discharges, allowing it to be used in harsh industrial environments. It also features undervoltage and ESD-protection circuitry, and an integrated charge pump circuit, simplifying the design of EMI-compliant solutions. The robust design and wide voltage range of this device make it an ideal solution for a variety of industrial, automotive, and consumer applications.
