Demonstration of Logic Gates

NOT Gate

NOT gates are simply inverters. They simply invert the input logic for the output. Here we are going to use 74LS04 IC for demonstration. This IC has 6 NOT gates in it. These SIX gate are connected internally.

Here is the breadboard image of a NOT gate circuit.

NAND Gate

This gate is mainly used in applications where there is a need for mathematical calculations. So calculators, computers and many digital applications use this gate. 

Here you can find the circuit diagram and detailed explanation of this Circuit: NAND Gate

XOR Gate

This gate is mainly used in applications where there is a need for mathematical calculations. So in calculators, computers and many digital applications use this gate.

Here we are going to use 74LS86 IC for demonstration, this chip has 4 EX-OR gates in it.

Here is the detailed explanation of XOR Gate Circuit
