How To Understand Not Gates In A Logic Ic

NOT gates are logic operators which may be found inside a CMOS IC. For new electronic enthusiasts, understanding logic gates sometimes becomes confusing because of the different shapes and terms involved with each of these gates.

How to Understand NOT Gates and use in electronic circuits.

Actually these are nothing but embedded tiny systems which basically have a set of outputs and normally a single output.

The output as the name suggests provides the final result or the desired function in response to the signals or commends provided to its inputs.

The input signals are always in the form of voltages, either a positive

or a negative, termed as logic high and logic low inputs respectively.

The corresponding outputs are also always given in the same form. The

positive input may be at the level of the supply voltage to the IC and the negative voltage is always a ground potential.

A NOT gate is the most fundamental system of the logic family, because it has a single input and a single output only. The input command provides an opposite result at the output. So if we apply a logic high at the input, we get a logic low at the output and vice versa. A number of interesting circuits can be built using NOT gates, which can be read here.
