HD74LS85

4-bit Magnitude Comparator;

This four bit magnitude comparator performs comparison of straight binary and straight BCD (8-4-2-1) codes. Three fully decoded decisions about two 4-bit words (A, B) are made and are externally available at three outputs. This device is fully expandable to any number of bits without external gates. Words of greater length may be compared by connecting comparators in cascade. The A B, A < B, and A = B outputs of a stage handling less-significant bits. The stage handling the least- significant bits must have a high-level voltage applied to the A β B input. The cascading path is implemented with only a two-gate-level delay to reduce overall comparison times for long words.
