Product details

RS232 transceiver for industrial serial links

The MAX3223EIDW is a full-duplex RS232 transceiver from Texas Instruments, packing two drivers and two receivers into a 20-SOIC package (0.295", 7.50mm width). 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.

Frequently asked questions

What is the difference between MAX3223EIDW and MAX3223EIPW?

The difference is the package: MAX3223EIDW uses the 20-SOIC wide-body (0.295", 7.50mm width) while MAX3223EIPW uses the 20-TSSOP (0.173", 4.40mm width). The SOIC is easier to hand-solder and inspect; the TSSOP saves board area. Electrical specs are identical.
