Product details

Rated for 5 Mbps, this part supports update rates fast enough for most sensor arrays and drive parameter uploads without pushing the cable into transmission-line territory. At that speed, stub lengths on the bus need to stay short — keep the drop from the main trunk under a few inches or the reflections will eat into the 50 mV hysteresis margin.

No AEC-Q100 rating here, so it is not aimed at under-hood automotive — keep it on the factory-floor side of the isolation barrier.

The narrow SOIC saves board area compared to the wider 7.5 mm SOIC variants, but the pin pitch is the same 1.27 mm, so rework is straightforward with a fine-tip iron or hot air.

Frequently asked questions

What is the data rate of SN65HVD35DG4?

The data rate is 5 Mbps. At this speed, keep stub lengths on the bus short to avoid reflections that could exceed the 50 mV hysteresis margin.

Is SN65HVD35DG4 compatible with RS485?

Yes, SN65HVD35DG4 supports both RS-485 and RS-422 protocols in full-duplex mode.

What is the alternative to SN65HVD35DG4?

Within the same 65HVD35 base family, pin-compatible variants exist with different data rates or temperature grades. For a direct drop-in with the same 5 Mbps and industrial temperature range, the SN65HVD35D is the standard alternative — verify the package suffix matches your footprint.
