It handles 500kbps data rate across the serial link, sufficient for legacy industrial equipment, point-of-sale terminals, and embedded debug consoles. The 3V to 5.5V supply range means it can sit on a 3.3V microcontroller bus without a separate level shifter. ## Receiver hysteresis and noise margin The receiver hysteresis is specified at 500 mV, which means the input threshold has a clean deadband that rejects noise picked up on long RS232 cable runs. In a noisy motor-drive cabinet or near a switching power supply, this hysteresis keeps the UART from seeing false start bits. ## Active production — sourcing posture The 20-SOIC wide-body package is a standard TI footprint, so date-code continuity across reel lots is predictable.","metaTitle":"MAX3223EIDW RS232 Transceiver 500kbps Full Duplex 20SOIC TI","metaDescription":"Texas Instruments MAX3223EIDW RS232 transceiver, 2/2 drivers/receivers, full duplex, 500kbps, 3V-5.5V supply, -40°C to 85°C, 20-SOIC.
