74HC85; 74HCT85 4-bit magnitude comparator Rev. 3 — 20 April 2018 1 Product data sheet 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 QAB, IA=B and IAB, QA=B and QAB A2 B2 IAB A1 B1 QAB 5 12 A1 QA>B 5 12 A1 QA=B 6 11 B1 QA=B 6 11 B1 10 A0 QAB output QA=B 6 A=B output QA B2 X X X X X H L L A3 = B3 A2 < B2 X X X X X L H L A3 = B3 A2 = B2 A1 > B1 X X X X H L L A3 = B3 A2 = B2 A1 < B1 X X X X L H L A3 = B3 A2 = B2 A1 = B1 A0 > B0 X X X H L L A3 = B3 A2 = B2 A1 = B1 A0 < B0 X X X L H L A3 = B3 A2 = B2 A1 = B1 A0 = B0 H L L H L L A3 = B3 A2 = B2 A1 = B1 A0 = B0 L H L L H L A3 = B3 A2 = B2 A1 = B1 A0 = B0 L L H L L H A3 = B3 A2 = B2 A1 = B1 A0 = B0 X X H L L H A3 = B3 A2 = B2 A1 = B1 A0 = B0 H H L L L L A3 = B3 A2 = B2 A1 = B1 A0 = B0 L L L H H L 8 Limiting values Table 4. Limiting values In accordance with the Absolute Maximum Rating System (IEC 60134).
