Aug 5, 1. Would appreciate any feedback from you? The datasheets of Cmos gates shows that they switch their output in only 50ns 0.

Aug 6, 5.

I got rid of the switch that shorts the output to ground, was using it as a reset. Aug 6, 6. The wave is not exactly square in shape.

Aug 7, 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.

What is wrong in this circuit? The diodes at the input protection of Cmos gates clamps the input voltage to 0. Dec 20, 10, 1, The resistor is not needed if the ICs use the same power supply voltage.

Hi beenthere, I have made a new circuit. No, create an account now. 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 absolute max supply for a high speed 74HC is 7V and they recommed a max of 6V. Aug 6, 7. Aug 6, 8.

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. Aug 6, 9.

Do you already have an account? The circuit supply voltage is 12v. I read about input protection http: Why do you use a very high value resistor 1M feeding the oscillator to the counter’s clock input? Yes, my password is: You might get better results with a different arrangement of the RC components – http: I have created the following image attached NAND gate oscillator using 2 gates.

I don’t know why your oscillator has a switch at its output that shorts the output to ground. Hi Audioguru, I changed the circuit as per your suggestion.

Aug 6, 4. Your simulation sofware is also wrong when it shows the very slow switching ramps 0.

Aug 5, 2. A CD will not blow up unless you connect the power supply backwards. You get oscillator and counter in one. I cc4011 notice the output in the simulator is same. NAND gate oscillator frequency calculation Posted by ukiceman in forum: Quote of the day. Your Yenka sim software doesn’t know if it is coming or going. Feb 17, 4, 1, Your simulation software is wrong because it shows the input going 4V higher than the positive supply and 4V below ground.

Your name or email address: You May Also Like: Aug 5, 3. Your oscillator has both inputs of the gates shorted together.
