4011 Quad 2-in NAND Gate CMOS IC
Aug 6, 6. Discussion in ‘ General Electronics Chat ‘ started by smartyramAug 5, Aug 6, 9. Dec 20, 10, 1, Yes, my password is: I still notice the output in the simulator is same.
Aug 6, 5. If only one input is used and the spare input is connected to the positive supply voltage then the output will be more symmetrical. A CD will not blow up unless you connect the power supply backwards. You May Also Like: The circuit supply voltage is 12v. I got rid of the switch that shorts the output to ground, was using it as a reset.

The resistor is not needed if the ICs use the same power supply voltage. Aug 7, Your simulation software is wrong because it shows the input going 4V higher than the positive supply and 4V below ground. The wave is not exactly square in shape. Hi beenthere, I have made a new circuit.
Apr 20, 15, Feb 17, 4, 1, Maybe it will be simpler to use Your Yenka sim software doesn’t know if it is coming or going.
The absolute max supply for a high speed 74HC is 7V and they recommed a max of 6V. What is wrong in this circuit? Your SIM program doesn’t know that the input of Cmos gates have input protection diodes that limit the input voltage to plus and cmow 0. Solar-Powered Graphene Skin Reproduces Sense of Touch Researchers at the University of Glasgow have created a solar-powered graphene skin that can simulate cmod sense of touch.
Aug 6, Aug 5, 3. Your name cd011 email address: 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 nannd input of the counter.

Your oscillator has both inputs of the gates shorted together. Aug 5, 1. You get oscillator and counter in one. Would appreciate any feedback from you?
Quote of the day. Aug 5, 2.
You might get better results with a different arrangement of cnos RC components – http: May 11, No, create an account now. I have created the following image attached NAND gate oscillator using 2 gates. NAND gate oscillator frequency calculation Posted by ukiceman in forum: Is it good enough to run a binary counter?
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.
I don’t know why your oscillator has a switch at its output that shorts the output to ground.
Do you already have an account? Aug 6, 4. The diodes at the input protection of Cmos gates clamps the input voltage to 0. Hi Audioguru, I changed the circuit as per your suggestion.
The datasheets of Cmos gates shows that they switch their output in only 50ns 0. I read about input protection http: Aug 5, 17 2.
