The MM54C85J883C is a 4-Bit Magnitude Comparator manufactured by National Semiconductor (now Texas Instruments). It is a monolithic complementary MOS (CMOS) integrated circuit designed to compare two 4-bit binary words. This device determines whether one 4-bit word is less than, equal to, or greater than the other.

Applications:

• Process Control Systems
• Instrumentation
• Digital measurement equipment
• Address decoding
• General logic comparison

Features:

• Compares two 4-bit binary words (A and B)
• Cascadable to expand comparison to longer words
• TTL compatible operation
• Low power consumption
• Three outputs indicate A>B, A=B, and A

Benefits:

• Simple digital magnitude comparison
• Expandable for comparing larger bit words
• Easy to interface with TTL logic systems
• Reduces power requirements in applications
• Direct output indications for comparison results

Additional Details:

The MM54C85J883C performs the comparison of two 4-bit binary words A and B and provides three mutually exclusive outputs indicating A > B, A < B, and A = B. The device is fully cascadable, meaning multiple comparators can be connected to compare words of greater lengths. Cascading is achieved by connecting the A>B, A
