It handles serial communication up to 120 Kbps. The supply range is 4.5V to 5.5V — this is a 5V-only part. Do not feed it 3.3V and expect the outputs to swing RS232 levels. The receiver hysteresis is 500 mV, which helps reject noise on long cable runs common in factory-floor serial links. ## 5V-only supply and commercial temperature range If the board lives in a heated cabinet or a server room, the commercial grade is fine. The 5V-only rail means the logic interface on the board side must tolerate or translate to 5V levels. If your UART is 3.3V, you will need level shifters or a different transceiver family. ## Active production, ROHS3, surface-mount package The package is a 20-SOIC wide-body (0.295-inch width, 7.50 mm), supplied in tape and reel or cut tape. That is a standard footprint; any assembly house that runs SOIC-20 can place it. No hot-air station needed for rework — a soldering iron and some wick will do.","metaTitle":"GD75323DWR RS232 Transceiver 5/3 Full Duplex 120Kbps 20-SOIC","metaDescription":"Texas Instruments GD75323DWR RS232 transceiver, full duplex, 5 drivers / 3 receivers, 120 Kbps data rate, 4.5V–5.5V supply, 20-SOIC.
