Working Principles

The MC14585BDR2 is a 4-bit magnitude comparator that compares two 4-bit binary numbers and determines their relationship. It utilizes CMOS technology, which allows for high-speed operation while consuming minimal power. The inputs A0-A3 and B0-B3 represent the bits of the two binary numbers to be compared. The outputs LT, EQ, and GT indicate whether the first number is less than, equal to, or greater than the second number, respectively. The carry output (C0) and borrow output (C1) are used for cascading multiple comparators.
