MC14585B  
4−Bit Magnitude Comparator  
The MC14585B 4−Bit Magnitude Comparator is constructed with  
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.  
Applications include logic in CPU’s, correction and/or detection of  
instrumentation conditions, comparator in testers, converters, and  
controls.
