MAX3221EIDBR Description

Short technical summary and product information.

The MAX3221EIDBR from Texas Instruments is a single driver, single receiver RS-232 solution designed for reliable serial communication. It operates from a single 3V to 5.5V VCC supply, making it versatile for various applications. This transceiver supports data signaling rates up to 250kbit/s and features robust ESD protection for its RS-232 pins, rated at +/-15kV HBM and +/-8kV to +/-15kV IEC 61000-4-2.

 

Key electrical characteristics include a low standby current of 1µA typical and the ability to accept 5V logic input with a 3.3V supply. An auto-power-down feature conserves power by disabling drivers when the receiver is disconnected or the remote driver is powered down. The device meets or exceeds TIA/EIA-232-F and ITU v.28 standards.

 

Packaged in a 16-pin SSOP, the MAX3221EIDBR is suitable for surface mount applications. Its operating temperature range is -40°C to 85°C, ensuring performance in demanding environments. The device is supplied in a 2,000-unit reel, ideal for automated assembly processes.
