DESCRIPTION
The HEF4585B is a 4-bit magnitude comparator which
compares two 4-bit words (A and B), whether they are ‘less
than’, ‘equal to’, or ‘greater than’. Each word has four
parallel inputs (A

Operation is not restricted to binary codes, the devices will
work with any monotonic code. The function table
