The 74HC85 SMD is a 4-bit magnitude comparator that can be expanded to almost any length. They perform comparison of two 4-bit binary, BCD or other monotonic codes and present the three possible magnitude results at the outputs (QA>B, QA=B and QAB, IA=B and IAB = LOW and IA=B = HIGH. For words greater than 4-bits, units can be cascaded by connecting outputs QA>B, QA=B and QA.
