8-Bit Magnitude Comparator (Equality Detector)
General Description
This equality detector utilizes advanced silicon-gate CMOS
technology to compare bit for bit two 8-bit words and indi-
cates whether or not they are equal The PeQ output indi-
cates equality when it is low A single active low enable is
provided to facilitate cascading of several packages and en-
able comparison of words greater than 8 bits
This device is useful in memory block decoding applica-
tions where memory block enable signals must be generat-
ed from computer address information
The comparator’s output can drive 10 low power Schottky
equivalent loads This comparator is functionally and pin
compatible to the 54LS68874LS688 All inputs are protect-
ed from damage due to static discharge by diodes to VCC
and ground
