8-Bit Magnitude Comparator September 1997 -Revised August 2003 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. Fanout (Over Temperature Range)
-Standard Outputs . 10 LSTTL Loads
-Bus Driver Outputs . 15 LSTTL Loads Wide Operating Temperature Range . -55oC to 125oC Ordering Information Balanced Propagation Delay and Transition Times Significant Power Reduction Compared to LSTTL
