Features  
Description  
• Cascadable  
The Harris CD74HC688 and CD74HCT688 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.  
• Fanout (Over Temperature Range)
