  • Half adder is a combinational logic circuit with two inputs and two outputs. It is the basic building block for addition of two “single” bit numbers. This circuit has two outputs namely “carry” and “sum”. Truth table of half adder is given below:
INPUT   OUTPUT  
A B Sum Carry
0 0 0 0
0 1 1 0
1 0 1 0
1 1 0 1

Logical Equation:

Sum= A’B + AB’ Carry= AB

Logical diagram is as follows:
