I have a flip flop at I have set up so it only cares about falling edges. I have a couple units however that when they get a little bit warmer, they start to trigger on the rising edge of the clock line. Any ideas on what is going on? I have looked at the scope trace, and zoomed in, the clock signal is going from 0 to 5 volts, with little time inbetween (aka 2v, to 3v, to 4v). Somewhere at around 3 volts though, the JK Flip Flop triggers on the rising edge instead of the falling edge as it should be. Why does the flip flop think the rising edge is a falling edge? Also, why does it behave this way when its warm, but if I try to cool the unit down a few degrees the unit acts as excepted?
Thanks
