I’m using 74HC76 74c76 that contains two jk. Do not, ever, disconnect the VCC pin when debugging, because that breaks chips. On CMOS parts, all unused inputs must be connected, directly or through a resistor, to either Vcc or ground, whichever dahasheet required to make the part work as required. I’m building a simple ring counter with two jk flip-flop. Sign up using Email and Password. Sign up or log in Sign up using Google.
It means that if I wire pin 5 to Vcc I got always 10 output. How do you ensure this?

Thanks for your advice. I’ve a button that sets the starting 1 in the first jk, so I think that the problem isn’t about Preset or Clear pin.

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. Email Required, but never shown.

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. About Preset and Clear pin I’m managing them well: This is my schematic very basic: If no what’s the matter of my circuit?
