Your name or email address: Aug 6, Would appreciate any feedback from you? Maybe it will be simpler to use cmow The resistor is not needed if the ICs use the same power supply voltage.

Apr 20, 15, I got rid of the switch that shorts the output to ground, was using it as a reset. NAND gate oscillator frequency calculation Posted by ukiceman in forum: Aug 6, 6. Your simulation software is wrong because it shows the input going 4V higher than the positive supply and 4V below ground. No, create an account now. I read about input protection http: 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 wave is not exactly square in shape.

CD – Quad 2-In NAND Gate

A CD will not blow up unless you connect the power supply backwards. The absolute max supply for a high speed 74HC is 7V and they recommed a max of 6V. May 11, Why do you use a very high value resistor 1M feeding the oscillator to the counter’s clock input? Your simulation sofware is also wrong when it shows the very slow switching ramps 0. Your oscillator has both inputs of the gates shorted together. Hi beenthere, I have made a new circuit.

NAND Gate Oscillator using CD4011

If only one input is used and the spare input is connected to the positive supply voltage then the output will be more symmetrical. 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. Aug 7, The circuit supply voltage is 12v.

Aug 6, 9. Hi Audioguru, I changed the circuit as per your suggestion.

I don’t cs4011 why your oscillator has a switch at its output that shorts the output to ground. What is wrong in this circuit?
