How To Understand Nand Gates In Electronic Circuits

NAND gates are logic functions that may be seen in a CMOS IC. For budding electronic noobs, grasping logic gates invariably becomes difficult to understand because of the various shapes and symbols possessed with each of these gate types.
Precisely these gates are nothing but built-in tiny operators which primarily have a bunch of outputs and mostly a single output.

The output, as the name refers to provides the actual result or the proposed operations in response to the triggers or signals applied to its input leads.


The input triggers are conventionally in the form of potential differences, that is, a

positive or a negative potential, called logic high and logic low signals respectively.

The consequent outputs are similarly always referred in the same terms. The positive input signal may be at the potential of the supply voltage of the IC and the negative voltage is imperatively a ground potential.

How to understand NAND gates:


A NAND gate is one


of the versatile systems of the logic family, and consists of two input leads and a single output lead. The input trigger in the sets of two is applied to the inputs of the gate.
Depending upon the application of the input sets of signals, the outputs logs a particular output logic state.
Typically if both the inputs are applied a logic high, the output becomes logic low, with both the inputs at logic low makes the output go high, however if the inputs are applied with opposite triggers, that is if one of the inputs is at logic low while the other is at logic high, the output stays at logic high irrespective of the orientation of the input signal levels.
