Features  
Description  
• Cascadable  
The ’HC688 and ’HCT688 are 8-bit magnitude comparators  
designed for use in computer and logic applications that  
require the comparison of two 8-bit binary words. When the  
compared words are equal the output (Y) is low and can be  
used as the enabling input for the next device in a cascaded  
application.
