Half adder is a one types of combinational logic circuit with two input and also have two output. It is basic building block for addition of two single bit numbers. This circuit has two outputs called as sum and carry.
The half adder circuit designed to add two single bit binary numbers A and B. Hence the truth table of a half adder is shown in fig.
- -S = AB + AB
