4 Bit Comparator Logic Circuit. Ic of digital comparator the integrated circuit ic available for 4 bit digital comparator is ic 7485. 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.
The figure below shows the pin diagram of ic7485 comparator. We will compare each bit of the two 4 bit numbers and based on that comparison and the weight of their positions we will draft a truth table. 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.
A comparator used to compare two binary numbers each of four bits is called a 4 bit magnitude comparator.
For more bit comparison more than one such ics can be cascaded. Ic of digital comparator the integrated circuit ic available for 4 bit digital comparator is ic 7485. This video contains the description about 1. A comparator used to compare two binary numbers each of four bits is called a 4 bit magnitude comparator.
