I have 2 questions about SN74AHCT14/AHCT family.
(1) Is it possible to input 5.5V when Vcc is power down(Vcc=0V)?
(2) Do AHCT families have 5V tolerant input?
I think AHC/AHCT have the function, but there is no description in the TI web site below.
I need to answer my customer as soon as possible, so your help would be appreciated.
