7485 (4-bit magnitude comparator)

7485 4-bit Magnitude Comparator PDIP-16

The 7485 4-Bit Magnitude Comparator is a high-performance CMOS digital logic IC that compares two 4-bit binary words and outputs signals indicating whether one word is greater than, less than, or equal to the other. Packaged in a standard 16-pin PDIP, this comparator supports expandability for wider word lengths through cascade inputs and outputs, making it suitable for complex digital systems and microprocessor interfaces.

It is widely used in arithmetic units, sorting logic, state machines, and decision-making circuits where high-speed, reliable binary magnitude comparison is required. The robust CMOS design ensures low power consumption and high noise immunity, compatible with standard TTL and CMOS logic voltage levels.

Features

• Compares two 4-bit binary numbers (A and B) and produces magnitude outputs.
• Outputs for A > B, A < B, and A = B for clear decision logic.
• Cascade inputs for expandability to larger bit-width comparisons.
• Standard PDIP-16 through-hole package for easy PCB integration.
• CMOS logic with low power consumption and high noise immunity.
• Suitable for TTL and CMOS mixed logic systems.
