It is designed for serial communication links where board space is tight and the supply rail can range from 3V to 5.5V, covering both 3.3V and 5V logic domains without a separate level shifter. Data rate is rated at 250kbps. The receiver hysteresis of 500 mV helps reject noise on longer cable runs. The package is 16-TQFN (5x5 mm). Surface-mount assembly is standard. ## Lifecycle and sourcing posture The MAX3221ECTE+ carries an Active lifecycle status and is ROHS3 compliant.","metaTitle":"MAX3221ECTE+ RS232 Transceiver, 250kbps, 1/1 Driver/Receiver","metaDescription":"MAX3221ECTE+ RS232 transceiver, full duplex, 250kbps data rate, 3V to 5.5V supply, 16-TQFN package.
