I have a logic IC. What will be happen if I Connect it’s input and output pins to values that aren’t correct value for example wiring a not gate’s input and output together ! I think that this IC will be damaged. How long it takes?
Thank you!

Yes, the IC may not die, but if - as you say - you connect the output to its own input on an inverting gate, then you may well end up with an oscillator with a "wild" (uncontrolled) frequency.
Well, the frequency will be determined by how long it takes for the signal to get from input to output (nano-seconds).
Reason: (start anywhere in time) input is low, that makes output high, your wire feeds that back to the input which gets high, makes the output low, and so on......

As long as you don't exceed the maximum voltage rating, you won't damage anything. You'll just get strange results. Tieing the output of an inverter back to its input will probably make an oscillator.

You have to consider that your working with voltages as a representative of a logical function, meaning its dependent on what your interfacing components are configured to do in response to these voltages. And of coarse you realize that any voltage routed to ground is a short circuit. As long as you do not exceed the amperage parameters of the IC there would be no damage.

It depends on the type of circuitry inside. Probably nothing would happen; but if you're using CMOS, it's probably already dead from static discharge from you handing it.
