SN74LS85  
4-Bit Magnitude  
Comparator  
The SN74LS85 is a 4-Bit Magnitude Camparator which compares  
two 4-bit words (A, B), each word having four Parallel Inputs (A –A ,  
0

B –B ); A , B 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” (O ), “A less  
A>B  
than B(O  
), “A equal to B” (O  
). Three Expander Inputs, I ,

The Truth Table on the following page describes the operation of the  
SN74LS85 under all possible logic conditions. The upper 11 lines  
describe the normal operation under all conditions that will occur in a  
single device or in a series expansion scheme. The lower five lines  
describe the operation under abnormal conditions on the cascading  
inputs. These conditions occur when the parallel expansion technique  
is used.
