HD74HC688

8-bit Magnitude Comparator

The HD74HC688 compares bit for bit two 8-bit words and indicates whether or not they are equal. The P=Qoutput 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. This
