SN65C1168E-SEP: If one of the drivers and/or receivers fails, is the other one isolated enough that it will still function?

Greetings!

My customer has the following questions about the SN65C1168EMPWSEP:

If one of the drivers and/or receivers fails, is the other one isolated enough that it will still function?

Are there specific failure modes where this is the case and others where it is not?

Thanks for your help!

Best regards,

Jim B

    Hi Jim,

    There is minimal shared circuitry between the channels, so for the most part a single-point failure that affects one would be unlikely to also affect the others.  Some exceptions would be cases where an output is short-circuited (as might occur due to stresses coupling through connector ports/cables, which could lead to heating in that particular output stage that could affect the die more globally) or where the ICC increases sharply (which, again, could have global effects due to heating or due to system-level concerns like VCC droop in response to the failure).
