**Ex-OR Function Realisation using NAND gates**

**Exclusive-OR Gates** is used mainly to build circuits that perform arithmetic operations and calculations especially **Adders** and **Half-Adders** as they can provide a “carry-bit” function or as a controlled inverter, where one input passes the binary data and the other input is supplied with a control signal.

Commonly available digital logic Exclusive-OR gate IC’s include:

- 74LS86 Quad 2-input

- CD4030 Quad 2-input

**7486 Quad 2-input Exclusive-OR Gate**

The **Exclusive-OR** logic function is a very useful circuit that can be used in many different types of computational circuits. Although not a basic logic gate in its own right, its usefulness and versatile have turned it into a standard logical function complete with its own Boolean expression, operator and symbol.
