Supply voltage range of 3V to 5.5V allows operation from common 3.3V or 5V rails without an external regulator. The receiver hysteresis of 500 mV provides noise immunity on the RS-232 bus. ## 16-SSOP package, surface-mount assembly Housed in a 16-SSOP package (5.30 mm body width, 0.209-inch pitch), the TRS3221ECDBR is a surface-mount device intended for automated PCB assembly. The 16-SSOP footprint is common across TI's RS-232 transceiver family, easing layout reuse. The commercial temperature grade (0°C to 70°C) limits deployment to controlled indoor environments; for extended temperature ranges, consider the industrial-grade variant TRS3221EIDBR. ## Active production, ROHS3 compliant ROHS3 compliance is confirmed, supporting lead-free assembly requirements. Available in Tape & Reel (TR) and Cut Tape (CT) packaging options for volume production or prototype quantities. Sourced per RFQ against your BOM line.","metaTitle":"TRS3221ECDBR RS-232 Transceiver 1/1 16-SSOP Texas","metaDescription":"TRS3221ECDBR RS-232 transceiver, full duplex, 250 kbps, 3V-5.5V supply, 16-SSOP.
