This is my schematic very basic: I’m building a simple ring counter with two jk flip-flop. Sign up using Email and Password.

For the Preset pin where you have a switch to eatasheet 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. Sign up or log in Sign up using Google.

On CMOS parts, all unused inputs must be connected, directly or through a resistor, to either Vcc ratasheet ground, whichever is required to make the part work as required. Post as a guest Name. JK1 and JK2 need to initialize in opposite states, don’t they? I initialize the first jk with 1 using a button and preset and clear pin.

How do you ensure this? It means that if I wire pin 5 to Vcc I got always 10 output. 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. 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.
