Overview

The half adder is a combinational circuit which adds two binary numbers and produces a sum and carry bit as output. If A and B are the input bits, then sum bit (S) is the X-OR of A and B and the carry bit (C) will be the AND of A and B. Half adder is the simplest of all adder circuit, but it has a major disadvantage.  The half adder can add only two input bits (A and B) and cannot add if there is a carry into the input.
