SEMICONDUCTOR TECHNICAL DATA

The MC14585B 4–Bit Magnitude Comparator is constructed with comple-

mentary 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.
