74HC85 4-bit Magnitude Comparator, DIP-16 Package
74HC85 4-bit Magnitude Comparator ā DIP-16 Package
The 74HC85 is a 4-bit magnitude comparator integrated circuit from the high-speed CMOS (HC) logic family. It compares two 4-bit binary words (A and B) and provides three active-high outputs indicating whether A is greater than, less than, or equal to B. Housed in a standard DIP-16 package, this IC is essential for digital arithmetic and control systems in electronics projects.

What is the difference between the 74HC85 and the 74LS85?
The 74HC85 uses high-speed CMOS technology, offering lower power consumption and a wider supply voltage range (2Vā6V) compared to the 74LS85 (LS-TTL, 5V only). Both are pin-compatible and functionally identical.
How do I cascade multiple 74HC85 ICs for larger bit comparisons?
Connect the A>B, A
