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.

This device contains protection circuitry to guard against damage due to high  
static voltages or electric fields. However, precautions must be taken to avoid  
applications of any voltage higher than maximum rated voltages to this  
high–impedancecircuit. For proper operation, V and V should be constrained
