General description
The 74HC85; 74HCT85 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 QA<B).

FEATUREs and benefits
• Wide supply voltage range from 2.0 to 6.0 V
• CMOS low power dissipation
