Hi TI:
I use a schmitt buffer and CD4013 to realize a long push button circuit.
Long press 1 second to toggle STB_CTRL signal.
short press will not change STB_CTRL.
I want to replace it with a schmitt input D Flip-flop 74HCS72,74HCS74.
One logic IC replace two parts.
But I found there is nonstable state on 74HCS72,74HCS74
But CD4013 do not have this nonstable state.
I only found 74HCS72 or 74HCS74 these two parts can have schmitt trigger input D flip flop.
I can not use one schmitt trigger input D flip flop 74HCS72 or 74HCS74 to replace schmitt buffer 74LVC1G17+CD4013?
Or CD4013 also have this nonstable state,but not written in the datasheet ?
Will this long push button circuit have some side effect?
best regards
