It will not operate from a 3.3V supply — the bus common-mode and differential output levels are specified for the 5V domain. If your microcontroller is 3.3V, you still need a 5V rail for the transceiver and level translation on the TXD/RXD pins. The base product number 65HVD251 family includes no 3.3V variant; that is the SN65HVD230 line. The ROHS3 compliance is confirmed. It comes in an 8-SOIC package with 0.154 inch body width (3.90 mm).","metaTitle":"TI SN65HVD251QDRQ1 CAN Transceiver, 1Mbps, AEC-Q100, 8-SOIC","metaDescription":"Texas Instruments SN65HVD251QDRQ1 half-duplex CANbus transceiver. 1Mbps data rate, 4.5V~5.5V supply, -40°C~125°C.

The package is the same 8-SOIC footprint. The non-Q1 variant lacks the AEC-Q100 certification, so for automotive BOMs the QDRQ1 is the correct drop-in replacement."},{"question":"Can SN65HVD251QDRQ1 be used in a 3.3V system?","answer":"No. The supply voltage range is 4.5V to 5.5V, so a 3.3V rail is outside the operating limits. The transceiver's bus output levels and receiver thresholds are designed for a 5V CANbus. If your system runs on 3.3V, look at the SN65HVD230 family which is specified for 3.3V operation."},{"question":"What is the difference between SN65HVD251QDRQ1 and SN65HVD230?","answer":"The primary difference is the supply voltage. The SN65HVD251QDRQ1 runs on 4.5V to 5.5V (5V CANbus), while the SN65HVD230 is a 3.3V transceiver. Both are half-duplex CANbus parts at 1Mbps, but the supply rail dictates which one fits your system's power architecture. The SN65HVD251QDRQ1 also carries AEC-Q100 qualification; the SN65HVD230 may or may not depending on the suffix."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/SN65HVD251QDRQ1","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/SN65HVD251QDRQ1 when reusing this data.
