Other Parts Discussed in Thread: SN65HVD33

Dear all,

I would like to know what are the failure modes for this part: output shorted  to ground, open circuit....

Is there any document that specifies the different failure modes and their probability?

Thanks in advance.

Best regards,

Nuba.

    Hi Nuba,

    The SN65HVD33 supports fail safe biasing for open, short, and bus idle conditions. Here is a blog that I wrote on the fail safe biasing topic. I discussing implementing external fail safe biasing but the idea is the same for a device that supports it. There are also plenty of application notes out their on this topic, a quick google search will bring a number of them back for you. Check this link for some literature.


    Please let me know if you have other questions?

    Thanks Michael,

    I was actually talking about what would be tha failure mode for this part when it fails. This part has a MTBF of 2.67x 10^9. I would like to know what is the state of the part when the failure occurs.

    Thanks in advance.

    Nuba.

    Hi Nuba,

    Failures like this are unpredictable, the device can break open or short. There is no real way to predict this type of failure. Unfortunately, I do not have a better answer as these things are random and there is not a ton of data out there on it.
