I have a circuit that contains panel mounted pushbuttons, PB1-3.
See attached.
U101A,B is a 74HCT174 Dual D Flip Flop. NOR's are 74HCT02.
There is about 5-10 inches of wire from each leg of each pushbutton
to the circuits on each PCB (2 PCBs').
The question:
Should I use a hex buffer as shown (dashed symbol) to buffer the signal? 74HCT07?
Or maybe I actually need additional buffers to each PB?
Suggestions?
thanks
