MC14585B
4−Bit Magnitude Comparator
complementary MOS (CMOS) enhancement mode devices. The circuit
has eight comparing inputs (A3, B3, A2, B2, A1, B1, A0, B0), three
cascading inputs (A < B, A = B, and A > B), and three outputs (A < B,
A = B, and A > B). This device compares two 4−bit words (A and B)
and determines whether they are “less than”, “equal to”, or “greater
than” by a high level on the appropriate output. For words greater than
4−bits, units can be cascaded by connecting outputs (A > B), (A < B),
and (A = B) to the corresponding inputs of the next significant
comparator. Inputs (A < B), (A = B), and (A > B) on the least significant
(first) comparator are connected to a low, a high, and a low, respectively.

Ratings are stress ratings only. Functional operation above the Recommended
Operating Conditions is not implied. Extended exposure to stresses above the
Recommended Operating Conditions may affect device reliability.
