- 2. Difference between Combinational and sequential circuits Combinational Sequential Output of any instance of time depends only upon the input variables Output is generated dependent upon the present input variables and also on the basis of past history of these inputs Memory unit is not required. i.e. it doesn’t allocate any memory to the elements. Memory unit is required. . i.e. it allocates any memory to the elements.
