74LS08 AND Gate IC : Pin Configuration & Its Applications

The 74LS08 is a quadruple 8-bit two-input AND integrated circuit. A gate AND gate is a digital circuit that converts one logic state to another.
Two logic state signals are used in the AND gate. The first is HIGH, also known as 3-5 Volts, and the second is LOW, also known as 0-2.6 Volts. Two input pins and one output pin are used by a single AND gate.
The output will also be HIGH and LOW, but it will only be HIGH if both input states are HIGH. The single AND gate are simple to construct using transistors, resistors, and diodes.

First of all, we will understand what is AND gate and what is its function
The AND gate is an important component of a digital logic circuit. When any of the input states is low, the AND gate’s output state is always low. Simply put, if any input value in the AND gate is set to 0, the output will always be low (0).
The AND gate’s logic or Boolean expression is the logical multiplication of inputs denoted by a full stop or a single dot as,
A.B=Y
When both inputs A and B are set to true, the value of Y is true.
