54688 Product details

Description

This equality detector utilizes advanced silicon-gate CMOS technology to compare bit for bit two 8-bit words and indicate whether or not they are equal The PeQ 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 device is useful in memory block decoding applications where memory block enable signals must be generated from computer address information The comparator comb
