74HC85 datasheet



The 74HC85 / 74HCT85 are high-speed Si-gate CMOS devices and are pin compatible with low power Schottky TTL (LSTTL). They are specified in compliance with JEDEC standard no. 7A.
The devices are 4-bit magnitude comparators 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.

The operation of the “85” is described in the function table, showing all possible logic conditions. The upper part of the table describes the normal operation under all conditions that will occur in a single device or in a series expansion scheme.


1. Serial or parallel expansion without extra gating

2. Magnitude comparison of any binary words

3. Output capability : standard

4. ICC category : MSI
