Description
CD4585BMS is a 4-bit magnitude comparator designed for use in computer and logic applications that require the comparison of two 4-bit words. This logic circuit determines whether one 4-bit word (Binary or BCD) is “less than”, “equal to” or “greater than” a second 4-bit word.

Features
• High Voltage Type (20V Rating)
• Expansion to 8, 12, 16 . . .4N Bits by Cascading Units
• Medium Speed Operation
    - Compares Two 4-Bit Words in 180ns (Typ.) at 10V
• 100% Tested for Quiescent Current at 20V
• Standardized Symmetrical Output Characteristics
