Product details

Full-duplex RS-485 at 23 Mbps — what this transceiver brings to the bus

23 Mbps and full duplex — why the data rate and wiring matter

At 23 Mbps, this part handles high-speed point-to-point links where a half-duplex part would waste bus-turnaround dead cycles. Full duplex means separate twisted pairs for transmit and receive, so the bus can sustain continuous back-to-back throughput without direction switching — critical for encoder feedback or high-speed data concentrators. The 50 mV hysteresis filters out reflections on unterminated stubs, giving the layout engineer some margin on stub length.

3.3 V supply and industrial temperature — rail and environment fit

The 14-SOIC footprint is a standard narrow-body (3.90 mm width), compatible with most automated assembly lines.

Frequently asked questions

What is the difference between SN65HVD33D and SN65HVD32D?

The SN65HVD33D is a full-duplex transceiver, while the SN65HVD32D is half-duplex. Both operate at 23 Mbps and share the same 3.3 V supply and 14-SOIC package, but the full-duplex SN65HVD33D uses separate transmit and receive pairs, eliminating bus-turnaround dead cycles. If your protocol requires simultaneous send/receive or you need to avoid direction switching overhead, the SN65HVD33D is the correct choice.
