MM54HC85 MM74HC85 4-Bit Magnitude Comparator November 1995 MM54HC85 MM74HC85 4-Bit Magnitude Comparator General Description The MM54HC85 MM74HC85 is a 4-bit magnitude comparator that utilizes advanced silicon-gate CMOS technology It is designed for high speed comparison of two four bit words This circuit has eight comparison inputs 4 for each word three cascade inputs (AkB AlB A e B) and three decision outputs (AkB AlB A e B) The result of a comparison is indicated by a high level on one of the decision outputs Thus it may be determined whether one word is ‘‘greater than ’’ ‘‘less than ’’ or ‘‘equal to’’ the other word By connecting the outputs of the least significant stage to the cascade inputs of the next stage words of greater than four bits can be compared In addition the least sign
