Aug 7, A CD will not blow up unless you connect the power supply backwards.

10pcs/lot CD4011BE DIP-14 CD4011 CMOS NAND GATES IC

If only one input is used and the spare input is connected to the positive supply voltage then the output will be more symmetrical. Aug 6, 5.

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. Is it good enough to run a binary counter?

Your simulation software is wrong because it shows the input going 4V higher than the positive supply and 4V below ground. Your SIM program doesn’t know cv4011 the input of Cmos gates have input protection diodes that limit the input voltage to plus and minus 0. Aug 6, 6. Apr 20, 15, NAND gate oscillator frequency calculation Posted by ukiceman in forum: You get oscillator and nwnd in one. The circuit supply voltage is 12v. What is wrong in this circuit?

I don’t know why your oscillator has a switch at its output that shorts the output to ground. 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.

Your simulation sofware is also wrong when it shows the very slow switching ramps 0. Aug 5, 1.

Aug 5, 3. Hi beenthere, I have made a new circuit. Dec 20, 10, 1, Yes, my password is: Hi Audioguru, I changed the circuit as per your suggestion. Feb 17, 4, 1, I got rid of the switch that shorts the output to ground, was using it as a reset. Quote of the day. Aug 5, 17 2. Your name or email address: Discussion in ‘ General Electronics Chat ‘ started by smartyramAug 5, You May Also Like: Maybe it will be simpler to use You might get better results with a different arrangement of the RC components – http: Why do you use a very high value resistor 1M feeding the oscillator to the counter’s clock input?


Aug 6, 4. 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. Aug 6, Your oscillator has both inputs of the gates shorted together. The datasheets of Cmos gates shows that they switch their output in only 50ns 0. Aug 6, 9.

The absolute max supply for a high speed 74HC is 7V and they recommed a max of 6V. I read about input protection http: Do you already have an account? I have created the following image attached NAND gate oscillator using cmls gates.

Your Yenka sim software doesn’t know if it is coming or going. Would appreciate any feedback from you?
