X74_518 is an 8-bit identity comparator with 16 data inputs for two 8-bit words (P7 - P0 and Q7 - Q0), data output (PEQ), and active-Low enable (G). When G is High, the PEQ output is Low. When G is Low and the two input words are equal, PEQ is High. Equality is determined by a bit comparison of the two words. When any of the two equivalent bits from the two words are not equal, PEQ is Low.
