MM74HC688 - 8-Bit Magnitude Comparator (Equality Detector)
The MM74HC688 equality detector utilizes advanced silicon-gate CMOS technology to compare bit for bit two 8-bit words and indicates whether or not they are equal.
The P=Q output indicates equality when it is LOW.
A single active low enable is provided to facilitate cascading of several packages and
