Product details

3.3 V CAN transceiver in a SOT-23-8 footprint

The part comes in an SOT-23-8 package, a compact surface-mount footprint suited for space-constrained PCBs in engine control units, sensor nodes, and actuator modules. With one driver and one receiver onboard, it handles a standard CAN node interface. The base product number is TCAN330, indicating it belongs to the family of 3.3 V CAN transceivers from TI.

Supply voltage — the 3.3 V rail is a hard boundary

The TCAN330DCNR is strictly a 3.3 V device. The 3.3 V operation aligns with low-power microcontrollers and reduces bus emission edge rates compared to 5 V transceivers.

It will function reliably in engine compartments, transmission controllers, and industrial motor drives where ambient temperatures exceed 85°C. The 125°C upper limit covers the hottest under-hood locations, but derating for self-heating at high bus traffic should still be checked against the application's thermal profile.

Frequently asked questions

What are the alternatives to TCAN330DCNR?

Within the same TI TCAN330 family, the TCAN330D is the same transceiver in a different package option. For a pin-compatible alternative from another manufacturer, the NXP TJA1051T/3 is a 3.3 V CAN transceiver in an SOIC-8 package, but it is not footprint-compatible with the SOT-23-8. Verify the pinout and package before substituting.
