Data sheet acquired from Harris Semiconductor SCHS196 CD74HC688, CD74HCT688 High Speed CMOS Logic 8-Bit Magnitude Comparator Description 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.
