CD54HC688, CD74HC688, CD54HCT688, CD74HCT688 Data sheet acquired from Harris Semiconductor SCHS196C September 1997 - Revised August 2003 High-Speed CMOS Logic 8-Bit Magnitude Comparator Description 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.
