The base product number is SN65H, and the SHKQ suffix identifies the high-temperature, ceramic-package version. ## What the 210°C rating means for the BOM A 210°C maximum operating temperature is well above the 150°C typical of automotive under-hood parts. This part is rated for the full range, not just storage — it is meant to function while hot. That makes it a candidate for engine-mounted ECUs, exhaust-side sensors, or downhole tools where ambient can exceed 175°C. The 8-CFP package is a ceramic flat-pack with gull-wing leads, surface-mountable but requiring a reflow profile that respects the ceramic body's thermal mass. The 1/1 driver/receiver count is standard for a single CAN node; if the design needs galvanic isolation, an isolated DC-DC and a digital isolator on the controller side are needed, as this transceiver itself is not isolated.","metaTitle":"TI SN65HVD233SHKQ CAN Transceiver, -55°C to 210°C, 1 Mbps","metaDescription":"Texas Instruments SN65HVD233SHKQ is a half-duplex CAN transceiver in a hermetic 8-CFP package.

They are not pin-compatible for a direct swap — the package footprint differs, and the temperature grade is different. If the board already uses the D variant and the temperature stays below 125°C, the D part is the correct fit. The SHKQ is for designs that need the extended temperature range and hermetic seal."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/SN65HVD233SHKQ","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/SN65HVD233SHKQ when reusing this data.
