I have a circuit with the following connections to the SN74LVC1G80:
pin 5 is connected to 3.3V
pin 3 is connected to GND
pin 1 (D) is connected to pin 4 (^Q)
pin 2 (CLK) is connected to the output of a debouncer part (MAX6816)
I am monitoring pin 2 and pin 4 on a scope.
Both pin2 and pin4 indicate 3.3V on the scope. When the switch input to the debouncer is briefly connected to GND, pin 2 drops to 0V and back up to 3.3V but pin 4 remains high. Pin 4 remains high even with multiple switch events.
Any ideas why pin 4 stays high?
Thanks
