PDF datasheet for the SN74LS684N, an 8-bit magnitude comparator from the low-power Schottky 74LS family, in the N plastic DIP package. At only 7.04 KB the file is very small and probably holds a brief summary or ordering page rather than full specifications. The comparator checks two 8-bit words and signals equality or greater-than, often for address decoding on older expansion cards. Use the pinout to probe both input buses and the active-low outputs, and check the enable conditions before you replace it.
