Now a day’s Reversible logic is playing a crucial role in designing of digital circuits and it is used in reducing power consumption in digital design. By regaining the bit loss it reduces the power consumption in digital circuits. Gate diffusion input (GDI) is a technique of low-power digital circuit design. This technique reduces the power consumption, delay, and transistor count by maintaining the complexity very low of logic design. In these paper a novel MUX and DEMUX has been presented, which can be extended up to 1:2n and 2n:1 respectively  and these are developed by using only one type of Reversible gate i.e. Fredkin Gate (FRG) and Not Gate. The simulations are done in H-Spice using 90nm technology.
