SN65HVD233-HT: exceeding the maximum temperature

Part Number: SN65HVD233-HT

Hi There

I have an application where I would like to runs CAN interface at 230 degrees for 20-30h

can this part exceed the datasheet maximum temperature but with reduced operating life?

Is there a cliff edge temperature where the device stops working completely?

Kind Regards

Martin

  • Hey Martin,

    An engineer has been assigned to this post and will get back to you by tomorrow.

  • thanks

    FYI, i understand you can't guarantee it performance outside the datasheet. But I'm interested if anyone at TI can say after 210 degrees the performance is degraded and at 240 degrees, for example, the part stops functioning entirely or suffers catastrophic failure etc

    kind regards

    Martin

  • Hi Martin,

    Thanks for your patience on this, you are correct that we can't guarantee performance outside of the recommended operating conditions of the datasheet. Since this device is the high temperature version, there is another group within TI who used to support this device, so I'm working with them to see if we have any test data and I will get back to this thread as soon as they respond.

    Please let me know if you have any other questions.

    Regards,

  • Hi Martin,

    I spoke with the team who used to support this device and characterized it, and they said characterization stopped at 210 degrees. So it doesn't look like we have any data available past this temperature and don't have documented data showing what kind of degradation would happen. Where that cliff of not working anymore isn't known, but I can say that loading and thus the amount of power consumed through the transceiver will also have an effect on the device's lifespan at these high temperatures.

    Again, thanks for your patience on this.

    Regards,

  • Ok, thanks for having a look
