I received a question from my customer about behavior of monostable multivibrator logic "SN74LV123A".
Customers are willing to use VCC = 3.3V, and input voltage Vi = 5V(typ) for their application.
Vcc(3.3V) < Vi(typ 5V) < 5.5V
- Is it OK to apply a input voltage larger than VCC? Or are there any max condition of Vih?
The recommended operating conditions only state high level input voltage as "Vih = VCC x 0.7 V (min)", but there are no max value listed.
