74HCT85 4 Bit Magnitude Comparator IC (74HCT85 IC)

The 74HCT85 is a high speed CMOS 4 bit magnitude comparator with TTL compatible input levels. It compares two 4 bit binary inputs and provides outputs indicating greater than, less than, or equal conditions.

This IC is used in digital comparison circuits, arithmetic logic units, and control systems where binary data comparison is required. It allows cascading for comparison of larger bit widths.
