MAX3221CDBR Description

Short technical summary and product information.

The MAX3221CDBR from Texas Instruments is a single-channel RS-232 line driver and receiver designed for reliable serial communication. It operates with a wide supply voltage range of 3V to 5.5V, making it versatile for various applications.

 

This transceiver supports data rates up to 250kbps and includes ±15kV ESD protection on its serial port pins, exceeding TIA/EIA-232-F and ITU V.28 standards. It features one driver and one receiver, with an auto-powerdown function to conserve energy when not in use, reducing standby current to a typical 1µA.

 

The device is available in a 16-SSOP package, suitable for surface mounting. It requires four small external capacitors for its charge-pump circuit. The MAX3221CDBR is designed to provide the electrical interface between an asynchronous communication controller and a serial port connector.
