Re: Driving an OP AMP input with no VCC

I have a similar question to one posted a few days ago. I am thinking of
driving an OP AMP running at 5V configured as a follower with a 4.0V input
via a 10K and there could be times where Vcc is removed while the input
remains. Is it possible that this could damage the IC and should I use a
74LCX541 buffer as previously discussed?

Best regards,

Depends on the OpAmp. Read the maximum input voltage spec. If it
defines maximum input as a relationship with VCC, then you may have
problems.

Be more precise in you question... OpAmp type, etc.
