Digital Comparators

Digital comparators are hardware that is used to compare the value of two numbers. It works by taking the two numbers in binary form, then identifying if the two numbers are equal or whether one is greater than or less than the other. Also known as a magnitude comparator, examples of digital comparator include the CMOS 4063 and 4585 and the TTL 7485 and 74682-'89. While the analogue equivalent of digital comparator is the voltage comparator. Digital comparators are common combinational logic circuits used in CPUs and microcontrollers. They form an important part of trade, engineering, science, technology, and quantitative research processes in many disciplines.
