I'm having trouble using a NO momentary switch to send clock edges to a J-Kbar flip flop, specifically the TI CD74AC109E(datasheet).
I have a switch between +5V and the clock pin, and also added a 10k\$\Omega\$ pulldown to the clock pin, so it stays at 0V while the switch is open.
However, when I close the switch, the output responds sporadically; I have the flip flop hooked up so it toggles the Q and Qbar outputs on every high edge on the clock pin, but it doesn't always do that.
I realize that this might be caused by the lack of debouncing for the switch, but as the switch isn't a tactile switch (doesn't go click click when pressed), and the sporadic behavior occurs even when I depress the switch (open it), which makes me think it might be a different problem.
Does anyone have any suggestions as to why this might be happening?
P.S. YouTube video demonstrating the issue I have. I've hooked up an LED to the Q pin to show the output.
