Texas Instruments SN65HVD10QDG4, RS422/RS485 transceiver, half-duplex, 32 Mbps, 3V–3.6V supply, -40°C to 125°C, 8-SOIC package.
| Parameter | Value |
|---|---|
| Type | Transceiver |
| Mounting | Surface Mount |
| Supply voltage | 3V ~ 3.6V |
| Protocol | RS422, RS485 |
| Operating temperature | -40°C~125°C |
| Duplex | Half |
| Package | Tube |
| Data rate | 32Mbps |
| Case | 8-SOIC (0.154\", 3.90mm Width) |
| Receiver hysteresis | 35 mV |
| Number of drivers (Receivers) | 1/1 |
The 35 mV of receiver hysteresis cleans up noise on long cable runs without external filtering.
The SN65HVD10QDG4 carries a Last Buy status. If you have an existing design using this exact order code, now is the time to secure lifetime buy quantities or qualify a replacement.
Yes, officially it is in Last Buy status. That means TI has stopped taking new orders for regular production, but a final purchase window is open. Once that window closes, the part becomes obsolete and only surplus/broker stock remains.
The closest pin-compatible alternative is the SN65HVD10D – same 8-SOIC package, same 3V–3.6V supply, same 32 Mbps data rate. Verify its current lifecycle status with TI before switching a production BOM.
Yes. The driver and receiver are specified for that supply, so no level shifting is needed when interfacing to a 3.3V UART or MCU.
No – the duplex is half. It has one driver and one receiver, so it can only drive or listen on a single pair at a time. For full-duplex RS-422 you need a part with two drivers and two receivers, like the SN65HVD11 or SN65HVD12 family.
