I still notice the output in the simulator is same.
You might get better results with a different arrangement of the RC components – http: Aug 6, 4. No, create an account now.

Aug 5, 2. Quote of the day. 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 cmso cause the ckos from the oscillator to be a triangle-wave at the clock input of the counter. Your SIM program doesn’t know that the input of Cmos gates have input protection diodes that limit the input voltage to plus and minus 0.
The diodes at the input protection of Cmos gates clamps the input voltage to 0. Your name or email address: Hi Audioguru, I changed the circuit as per your suggestion.
Do you already have an account? Aug 5, 3. The wave is not exactly square in shape. I got rid of the switch that shorts the output to ground, was using it as a reset.
Your simulation sofware is also wrong when it shows the very slow switching ramps 0. The circuit supply voltage is 12v. Hi beenthere, I have made a new circuit.
A CD will not blow up unless you connect the power supply backwards. Is it good enough to run a binary counter? I don’t know why your oscillator has a switch at its output that shorts the output to ground.
May 11, Aug 6, 8. You get oscillator and counter in one. The datasheets of Cmos gates shows that they switch their output in only 50ns 0. Dec 20, 10, 1, Maybe it will be simpler to use Solar-Powered Graphene Skin Reproduces Sense of Touch Researchers at the University of Glasgow have created a solar-powered graphene skin that can simulate the sense of touch.

I read about input protection http: Aug 6, 6. Your simulation software is wrong because it shows the input going 4V higher than the positive c4011 and 4V below ground.
Your Yenka sim software doesn’t know if it is dmos or going. If only one input is used and the spare input is connected to the positive supply voltage then the output will be more symmetrical.
I have created the following image attached NAND gate oscillator using 2 gates.

Aug 5, 1. Feb 17, 4, 1, The absolute max supply for a high speed 74HC is 7V and they recommed a max of 6V. Aug 7, What is wrong in this circuit? Your oscillator has both inputs of the gates shorted together. Aug 6, 7. Yes, my password is:
