Overview
MC54/74F85 4-BIT MAGNITUDE COMPARATOR The MC54/74F85 is a 4-Bit Magnitude Comparator which compares two 4-Bit words (A0-A3, B0-B3), A3, B3 being the most significant inputs.
Operation is not restricted to binary codes; the device will work with any monotonic code.
Three Outputs are provided: “A greater than B” (0A > B), “A less than B” (0A < B), “A equal to B” (0A = B).
Three Expander Inputs, IA > B, IA < B, IA = B, allow cascading without external gates.
For proper compare operation, the Expander Inputs to the least significant position must be connected as follows: IA < B = IA > B = L, IA = B = H.
For serial (ripple) expansion the 0A > B, 0A < B Outputs are connected respectively to the IA...
