**Introduction-**

InÂ digital circuitÂ theory,Â **combinational logic**Â (sometimes also referred to asÂ **Â combinational circuits**) is a type ofÂ digital logicÂ which is implemented by Boolean circuits, where the output is aÂ pure functionÂ of the present input only.Whereas in sequential circuits , the output depends on present state of input and previous states of input.Â In other words, sequential logic hasÂ *memory*Â while combinational logic does not.
