Product details

Half-duplex RS485 transceiver for 3.3V industrial buses

The Texas Instruments SN65HVD11QDR is a half-duplex RS422/RS485 transceiver in an 8-SOIC package, designed for differential data buses up to 10 Mbps.

At 10 Mbps this transceiver supports high-speed polling cycles and fast data-logging links. The half-duplex architecture means the driver and receiver share the same pair, so the bus turnaround time matters — the SN65HVD11QDR switches direction cleanly without extra dead-time delays, keeping throughput up for protocols like Modbus RTU at high baud rates. The 35 mV receiver hysteresis filters out reflections on unterminated stubs, which is a practical help when the cable run is longer than the ideal termination point.

Frequently asked questions

What is the equivalent or replacement for SN65HVD11QDR?

Within the same TI family, the SN65HVD11 (non-Q suffix) is functionally identical but in a different ordering option. For a pin-compatible alternative, the SN65HVD12 offers a lower data rate of 1 Mbps; if you need higher speed, the SN65HVD10 runs at 32 Mbps. All share the same 8-SOIC footprint and 3.3V supply range.
