What this CAN transceiver is — and the gotcha that trips up first-time users
It handles one driver and one receiver, with 100 mV of receiver hysteresis to reject bus noise. Running it from a 5 V rail exceeds the absolute maximum and will damage the part.
Automotive grade — why it matters beyond the label
The Q1 suffix means this part went through AEC-Q100 qualification, which includes extended temperature cycling, high-temperature operating life, and ESD stress tests beyond the commercial-grade SN65HVD230DR. If your design targets under-hood or engine-adjacent environments where the ambient can hit 125°C, the QDRQ1 is the version to specify. The commercial DR variant is not rated for those conditions.
Package and footprint — standard 8-SOIC, no surprises
The footprint is the industry-standard SOIC-8, shared with many other CAN transceivers from TI, NXP, and Microchip. If you are replacing a 5 V CAN transceiver on an existing board, verify the supply rail first — the pinout is the same, but the voltage is not.
Lifecycle — active, no end-of-life concern
TI lists the SN65HVD230QDRQ1 as Active. For production programs that need a stable, long-term supply, this is a safe choice — no forced redesign on the horizon.
