Product details

CAN bus transceiver for 3.3 V automotive and industrial networks

The receiver includes 100 mV of hysteresis to reject noise on the differential bus, which helps keep the data intact when the cable picks up alternator whine or motor-drive hash.

The supply range of 3.0 V to 3.6 V matches the rail of a 3.3 V CAN controller directly, so no level shifter is needed between the controller's TX/RX pins and the transceiver. The part is not rated for 5 V logic on the bus side — the CANH/CANL pins are differential, but the logic interface expects 3.3 V levels. If your controller runs at 5 V, you will need a translation stage or a different transceiver rated for that supply.

For existing BOMs that already use this part, the supply channel is stable through standard distribution.

Frequently asked questions

Is SN65HVD234QDRQ1 a direct replacement for SN65HVD230?

The SN65HVD234QDRQ1 is a pin-compatible alternative to the SN65HVD230 within the same TI CAN transceiver family. Both are half-duplex, 1 Mbps parts in the same 8-SOIC footprint and 3.3 V supply range. The key difference is the AEC-Q100 qualification on the SN65HVD234QDRQ1, which adds automotive-grade temperature and reliability testing. If the original BOM used the SN65HVD230 in an automotive or high-temperature environment, the SN65HVD234QDRQ1 is a drop-in upgrade. For non-automotive designs, either part works, but the QDRQ1 variant carries the extended temperature rating.

Does SN65HVD234QDRQ1 work with 3.3V CAN controllers?

Yes, the SN65HVD234QDRQ1 is designed for 3.3 V CAN controllers. Its supply voltage range of 3.0 V to 3.6 V matches the typical 3.3 V rail, and the logic-level inputs (TXD, RXD) are compatible with 3.3 V CMOS logic levels. No external level translation is required when paired with a 3.3 V CAN controller.

Is SN65HVD234QDRQ1 RoHS and AEC-Q100 certified?

The SN65HVD234QDRQ1 is AEC-Q100 qualified, as indicated by the 'Q1' suffix in the order code, confirming it meets automotive-grade reliability standards including extended temperature range and qualification testing. The part is also RoHS-compliant per TI's standard lead-free plating for this product family.
