74HC85 (4-bit Magnitude Comparator)

Overview

The 74HC85 is a high-speed CMOS 4-bit magnitude comparator that compares two 4-bit binary words (A and B) and determines whether A is greater than B, A is less than B, or A equals B. This IC is essential for digital logic circuits that require numerical comparisons, such as in ALUs, digital control systems, and address decoding.

Key Features

• 4-bit magnitude comparison with three outputs: A>B, A<B, A=B
• High-speed operation compatible with TTL logic
• Wide operating voltage range: 2V to 6V
• Active-high outputs for easy interfacing
• Standard 16-pin DIP package for breadboard and PCB use
• Low power consumption typical of CMOS technology
• Expandable to 8-bit or more by cascading multiple ICs

Technical Specifications

• Bits: 4
• Type: Magnitude Comparator
• Output: Active High
