Product details

Active production, automotive-rated CAN transceiver for 5V buses

It handles the full CAN 2.0B bit rate of 1 Mbps and integrates a 100 mV receiver hysteresis for noise rejection on the differential bus.

Temperature range and AEC-Q100 — what they mean for deployment

For a motor-drive CAN node or an engine-control module, this is the temperature grade you need.

Supply rail and bus timing

The 1 Mbps data rate supports high-speed CAN 2.0B frames with a 500 ns bit time — adequate for real-time control loops and diagnostic buses. The 100 mV hysteresis on the receiver input helps reject common-mode noise on long twisted-pair runs.

Frequently asked questions

Is SN65HVD251DG4 equivalent to SN65HVD251D?

The SN65HVD251D is the same base device (65HVD251) in a different ordering code variant. The DG4 suffix indicates a specific packaging and lead-free finish option. Both share the same CAN transceiver core, pinout, and 1 Mbps data rate. For a direct cross-reference, compare the full datasheet ordering table to confirm the package and temperature grade match your BOM.

Does SN65HVD251DG4 support 1Mbps CAN?

Yes, the part is rated for a data rate of 1 Mbps, which is the maximum bit rate for CAN 2.0B.

Is SN65HVD251DG4 compatible with 5V logic?

For 3.3 V controllers, check the input logic thresholds in the datasheet.
