Texas Instruments SN65HVD53DRG4, RS422/RS485 Transceiver, Full-Duplex, 25 Mbps, 4.5V~5.5V, -40°C~85°C, 14-SOIC, Tape & Reel.
| Parameter | Value |
|---|---|
| Type | Transceiver |
| Mounting | Surface Mount |
| Supply voltage | 4.5V ~ 5.5V |
| Protocol | RS422, RS485 |
| Operating temperature | -40°C~85°C |
| Duplex | Full |
| Package | Tape & Reel (TR) |
| Data rate | 25Mbps |
| Case | 14-SOIC (0.154\", 3.90mm Width) |
| Receiver hysteresis | 50 mV |
| Number of drivers (Receivers) | 1/1 |
The receiver includes 50 mV of hysteresis to reject noise on long cable runs, a practical margin for factory-floor wiring.
If your system rail is 3.3 V, you need a level translator or a different transceiver. The 14-SOIC footprint is a standard width (3.90 mm body), compatible with most SOIC-14 land patterns.
Yes, the SN65HVD53DRG4 is a full-duplex transceiver, meaning it can transmit and receive simultaneously on separate twisted pairs. This is a key differentiator from half-duplex RS485 parts that require bus-turnaround control.
