where memory block enable signals must be generated from computer address information
The comparator combines the low po.
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 facilit.
