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.

This MM74HC688 is useful in memory block decoding applications, where memory block enable signals must be generated from computer address information.

The comparator MM74HC688's output can drive 10 low power Schottky equivalent loads. This comparator is functionally and pin compatible to the 74LS688. All inputs are protected from damage due to static discharge by diodes to VCC and ground.
