About Preset and Clear pin I’m managing them well: Sign up using Facebook. I’m building a simple ring counter with two jk flip-flop.

Thanks for your advice. Post as a guest Name. Home Questions Tags Users Unanswered. Without a resistor in series with each LED is is likely that the corresponding Q output is being dragged down to a voltage that is not high enough to be recognized as a legitimate high level by the following J input.
Email Required, but never shown. JK1 and JK2 need to initialize in opposite states, don’t they?
The problem is that in the circuit that I’m observing on my desk the ring counter only works when pin 5 Vcc is unwired.
It means that if I wire pin 5 to Vcc I got always 10 output. On CMOS parts, 47hc76 unused inputs must be connected, directly or through a resistor, to either Vcc or ground, whichever is required to make the part work as required.

For the Preset pin where you have a switch to pull it to ground, you must also have a resistor 5K – 10K to Vcc to ensure the preset pin is high when the switch is not taking it low. I’ve a button that sets the starting 1 in the first jk, so I think that the problem isn’t 74hc67 Preset or Clear pin. This is my schematic very basic: If no what’s the matter of my circuit? I’m using 74HC76 integrated that contains two 74jc76.
