  • SN65HVD230: Can one CAN transceiver be powered off 5V while another transceiver on the bus is powered off of 3.3V?

    TI Thinks Resolved
    Part Number: SN65HVD230 Hi there, are there any possible issues with having one upstream SN65HVD230 running at 5V, while other CAN nodes with SN65HVD230 are running at 3.3V? Any potential backfeeding issues? Or does the transceiver know to use the correct…

  • SN65HVD230: Are there any grounding potential considerations using multiple non-isolated XCVRs with an isolated XCVR on the same CAN bus?

    Part Number: SN65HVD230 Other Parts Discussed in Thread: TCAN334 , Hello, can multiple non-isolated SN65HVD230D CAN XCVRs be used with an upstream isolated CAN XCVR without any issues? I am currently experiencing an issue where there is coupled switching…

  • SN65HVD230: vref is not vcc/2

    Part Number: SN65HVD230 I have been using the SN65HVD230 successfully for several years now, on some of the latest run of prototype boards (only 42 built) the xcvr is behaving very strangely. In the circuit, vref is tied to the contacts of two solid state…

  • SN65HVD230: Communicate between SN65HVD230 and SN65HVD251

    TI Thinks Resolved
    Part Number: SN65HVD230 Other Parts Discussed in Thread: SN65HVD251 , Because of the SN65HVD230 has shortage issue, so some of device need to change the CAN to SN65HVD251. If one side we use SN65HVD230(VCC is 3V ~3.6V) and the other side is SN65HVD251(VCC…

  • SN65HVD230: CANH and CANL short circuit and IC Failure

    TI Thinks Resolved
    Part Number: SN65HVD230 Hi, We have used CAN SN65HVD230 in our Vehicle Tracking Device board. Testing is done in Lab, using a CAN to USB convertor and a PC. Worked fine. We are facing lot of failures of CAN IC in multiple vehicles which consist of multiple…
