Statistics: 11 inputs; 3 outputs; 33 gates;

Function: The 74L85 magnitude comparator can be functionally modeled as above. This is a simplification of implementing a magnitude comparator by a carry function with an inverted input bus as shown here. Using this concept, common elements of the three comparator functions A < B, A > B, and A = B are combined to construct the model shown above, which maps directly onto the gate-level realization of the 74L85.
