Types of AND Gates
There are two types of AND gates, based on the number of inputs
2-Input AND gate
It takes 2 inputs and the truth table will have 22 = 4 possible combinations. The truth table of 2 input AND gate is as follows:
X=A⋅B
3-Input AND Gate
It has three inputs and only one output. There are 23 = 8 combinations of input and output.
X=A⋅B⋅C
AND Gate
Logic gates are small digital switching circuit that determines the output of two or more inputted functions in Binary format. Logical ‘1’ means ‘True’ or ‘High’ in nature, whereas logical ‘0’ means ‘False’ or ‘Low’ in nature. Based on different logical operations, the output differs. There can be many inputs in a logic gate but there will be only one output. Each logic gate has its own truth table which represents all the combinations of input and output.
