All - I have a few questions about the subject IC.
I have been told that this IC can be damaged if there are logic inputs in the absence of Vcc. Is this correct?
If so, are there subtle failures, for example, changes in threshold, logic levels, propagation delays, etc?
What I'm trying to determine is, short of a catastrophic failure, can there be lesser failure modes that may not be directly obvious?
Thanks,
Dick Berg
