MM54C85MM74C85 4-Bit Magnitude Comparator

General Description

The MM54C85MM74C85 is a four-bit magnitude compara-

tor which will perform comparison of straight binary or BCD

codes The circuit consists of eight comparing inputs (A0

and determines whether they are ‘‘greater than’’ ‘‘less

than’’ or ‘‘equal to’’ each other by a high level on the appro-

priate output For words greater than four-bits units can be

addition the least significant stage must have a high level
