74F85 Datasheet (Philips) - 4-bit magnitude comparator

74F85, 4-bit magnitude comparator

The 74F85 is a 4-bit magnitude comparator that can be expanded to almost any length.

It compares two 4-bit binary, BCD, or other monotonic codes and presents the three possible magnitude results at the outputs.

The 4-bit inputs are weighted (A0 *A3) and (B0 *B3) where A3 and B3 are the
