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 clock input of the counter.

The diodes at cd0411 input protection of Cmos gates clamps the input voltage to 0. I don’t know why your oscillator has a switch at its output that shorts the output to ground. Apr 20, 15, You might get better results with a different arrangement of the RC components – http: Aug 5, 1.

Aug 6, 6. Why do you use a very high value resistor 1M feeding the oscillator to the counter’s clock input? The wave is not exactly square in shape. I still notice the output in the simulator is same. May 11, No, create an account now. 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 circuit supply voltage is 12v. Do you already have an account?

CD – Quad 2-In NAND Gate

Hi beenthere, I have made a new circuit. A CD will not blow up unless you connect the power supply backwards. Aug 5, 2. Aug 6, The absolute max supply for a high speed 74HC is 7V and they recommed a max of 6V.

What is wrong in this circuit? The datasheets of Cmos gates shows that they switch their nabd in only 50ns 0.

Aug 7, I have created the following image attached NAND gate oscillator using 2 gates. Aug 6, 5. Feb 17, 4, 1, Your simulation sofware is also wrong when it shows the very slow switching ramps 0. Hi Audioguru, I changed the circuit as per your suggestion.

NAND gate oscillator frequency calculation Posted by ukiceman in forum: If only one input is used and the spare input is connected to the cmls supply voltage then the output will be more symmetrical. Your oscillator has both inputs of the gates shorted together.

Aug 5, 17 2. Dec 20, 10, 1, Your simulation software is wrong because it shows the input going 4V higher than the positive supply and 4V below ground. Aug 6, 7. Quote of the day.

Yes, my password is: Aug 6, 8. Would appreciate any feedback from you? C,os got rid of the switch that shorts the output to ground, was using it as a reset.

Aug 5, 3. You get oscillator and counter in one. Maybe it will be simpler to use The resistor is not needed if the ICs use the same power supply voltage. Is it good enough to run a binary counter?

Aug 6, 9. I read about input protection http:
