DESCRIPTION HCF4585B is a monolithic integrated circuit fabricated in Metal Oxide Semiconductor technology available in DIP and SOP packages. HCF4585B is a 4-bit magnitude comparator designed for use in computer and logic applications that require the comparison of two 4-bit words. This logic circuit determines whether one 4-bit word (Binary or BCD) is "less than", "equal to" or "greater than" a second 4-bit word.

HCF4585B has eight comparing inputs (A3, B3 through A0, B0), three outputs (AB) and three cascading inputs (AB) that permit system designers to expand the comparator function to 8, 12, 16...4N bits. When a single HCF4585B is used, the cascading inputs are connected as follows: (AB) = high. Cascading these units for comparison of more than 4 bits is accomplished as shown in Typical application.
