Your simulation sofware is also wrong when it shows the very slow switching ramps 0. The 1M resistor between the oscillator and counter is not required and might stop the circuit from working because it will combine with stray capacitance between wires and cause the square-wave from the oscillator to be a triangle-wave at the nans input of the counter.

If only one input is used and the spare input is connected to the positive supply voltage then the output will be more symmetrical. Hi Audioguru, I changed the circuit as per your suggestion. Yes, my password is: Aug 7, Aug 6, najd The resistor is not needed if the ICs use the same power supply voltage.

Aug 6, 5. Apr 20, 15, Your Yenka sim software doesn’t know if it is coming or going.
A CD will not blow up unless you connect the power supply backwards. Would appreciate any feedback from you? Aug 5, 17 2. Aug 5, 3. Do you ckos have an account? NAND gate oscillator frequency calculation Posted by ukiceman in forum: Is it good enough to run a binary counter? The diodes at the input protection of Cmos gates clamps the input voltage to 0.
No, create an account now. Your name or email address: Quote of the day.
The circuit supply voltage is 12v. You get oscillator and counter in one.
Aug 6, 4. The wave is not exactly square in shape. Aug 5, 1. Maybe it will be simpler to use Your oscillator has both inputs of the gates shorted together.
