4 Bit Comparator Logic Diagram. It consists of eight inputs each for two four bit numbers and three outputs to generate less than equal to and greater than between two binary numbers. 4 bit magnitude comparator.
A comparator used to compare two binary numbers each of four bits is called a 4 bit magnitude comparator. Thus for 4 bit comparator the inputs will be 2x4 8 inputs and the entries in the truth table will be 2 2x4 2 8 256.

The output of comparator is usually 3 binary variables indicating. The figure below shows the pin diagram of ic7485 comparator. So we will do things a bit differently here. This video contains the description about 1.
