Your simulation sofware is also wrong when it shows the very slow switching ramps 0. Your name or email address: Why do you use a very high value resistor 1M feeding the oscillator to the counter’s clock input?

CD4011 – Quad 2-In NAND Gate

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. Maybe it will be simpler to use You might get better results with a different arrangement cd4011 the RC components – http: Hi beenthere, I have made a new circuit. Dec 20, 10, 1, You get oscillator and counter in one.

The wave is not exactly square in shape. Aug 5, 3. Aug 6, 7. Yes, my password is: You May Also Like: I don’t know why your oscillator has a switch at its output that shorts the output to cmso. Apr 20, 15, Aug 5, 1.

  BGI 7004 PDF

Aug 7, Aug 6, 6. 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.

A CD will not blow up unless you connect the power supply backwards. Discussion in ‘ General Electronics Chat ‘ started nanc smartyramAug 5, I read about input protection http: Aug 6, 5. Quote of the day. The absolute max supply for a high speed 74HC is 7V and they recommed a max of 6V.

I got rid of the switch that shorts the output to ground, was using it as a reset. nnad

Practical Electronics/IC/4011

I still notice the output in the simulator is same. Aug 6, 8. Aug 6, 4. Your simulation software is wrong because it shows the input going 4V higher than the positive supply cjos 4V below ground.

What is wrong in this circuit? The resistor is not needed if the ICs use the same power supply voltage.

The diodes at the input protection of Cmos gates clamps the input voltage to 0. No, create an account now.


CD Quad 2-Input NAND Gate CMOS IC Free IC Base for: : Electronics

Your Yenka sim software doesn’t know if it is coming or going. The datasheets of Cmos gates shows that they switch their output in only 50ns 0. NAND gate oscillator frequency calculation Posted by ukiceman in forum: May 11, Aug 5, 17 2. If only one input is used and the spare input is connected to the positive supply voltage then the output will be more cnos.

Feb 17, 4, 1, Aug 6, 9. Would appreciate any feedback from you?

Do you already have an account? The circuit supply voltage is 12v. Your oscillator has both inputs of the gates shorted together.

I have created the following image attached NAND gate oscillator using 2 gates. 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 5, 2. Aug 6, Is it good enough to run a binary counter?

Hi Audioguru, I changed the circuit nsnd per your suggestion.
