CD QUAD 2-INPUT NAND GATE – Velleman – Wholesaler and developer of electronics
The wave is not exactly square in shape. Your simulation sofware is also wrong when it shows the very slow switching ramps 0.
Aug 5, 3. Aug 5, 2. Aug 6, 4. I got rid of the switch that shorts the output to ground, was cmps it as a reset.
The resistor is not needed if the ICs use the same power supply voltage. Maybe it will be simpler to use Do you already have an account? Aug 6, NAND gate oscillator frequency calculation Posted by ukiceman in forum: Aug 6, 5.
Dec 20, 10, 1, Hi Audioguru, I changed the circuit as per your suggestion. Would appreciate any feedback from you? 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 mcos and cause the square-wave from the oscillator to be a triangle-wave at the clock input of the counter.
Hi beenthere, I have made a new circuit. Aug 5, 1.
CD Quad 2-Input NAND Gate CMOS IC Free IC Base for: : Electronics
Your oscillator has both inputs of the gates shorted together. I don’t know why your oscillator has a switch at its output that shorts the output to ground. Your name or email address: Discussion in ‘ General Electronics Chat ‘ started by smartyramAug 5, I have created the following image attached NAND gate oscillator using 2 gates. A CD will not blow up unless you connect the power supply backwards. Aug 7, Yes, my password is: The diodes at the input protection of Cmos gates clamps the input voltage to 0.

The circuit supply voltage is 12v. May 11, Quote of the day.
Aug 5, 17 2. Your SIM program doesn’t know that the input cd40011 Cmos gates have input protection diodes that limit the input voltage to plus and minus 0. Aug 6, 9. You get oscillator and counter in one.
Your simulation software is wrong because it shows the input going 4V higher than the positive supply and 4V below ground. Your Yenka sim software doesn’t know if it is coming or going.
Feb 17, 4, 1, I still notice the output in the simulator is same.
What is wrong in this circuit? The absolute max supply for a high speed 74HC is 7V and they recommed a max of 6V. If only one input is used and the spare input is connected to the positive supply voltage then the output will be more symmetrical.

Is it good enough to run a binary counter? 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, 7. Why do you use a very high value resistor 1M feeding the oscillator to the counter’s clock fmos
