8位数值比较器(平等探测器) 8-Bit Magnitude Comparator Equality Detector
General Description
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 enable comparison of words greater than 8 bits.
