74HC85; 74HCT85
4-bit magnitude comparator
Rev. 4 — 4 August 2021
Product data sheet
1. 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). The 4-bit inputs are
weighted (A0 to A3 and B0 to B3), where A3 and B3 are the most significant bits. For proper
compare operation the expander inputs (IA>B, IA=B and IA<B) to the least significant position must
be connected as follows: IA<B = IA>B = LOW and IA=B = HIGH. For words greater than 4-bits, units
can be cascaded by connecting outputs QA>B, QA=B and QA<B to the corresponding inputs of
the significant comparator. Inputs include clamp diodes. This enables the use of current limiting
resistors to interface inputs to voltages in excess of VCC
.

[3] CPD is used to determine the dynamic power dissipation (PD in μW).
PD = CPD × VCC 2 × fi + Σ (CL × VCC 2 × fo) where:
fi = input frequency in MHz;

Definitions
Limiting values — Stress above one or more limiting values (as defined in
the Absolute Maximum Ratings System of IEC 60134) will cause permanent
damage to the device. Limiting values are stress ratings only and (proper)
operation of the device at these or any other conditions above those
given in the Recommended operating conditions section (if present) or the
Characteristics sections of this document is not warranted. Constant or
repeated exposure to limiting values will permanently and irreversibly affect
the quality and reliability of the device.

internal review and subject to formal approval, which may result in
modifications or additions. Nexperia does not give any representations or
warranties as to the accuracy or completeness of information included herein
and shall have no liability for the consequences of use of such information.
