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 (A<B, A=B, A>B)
and three cascading inputs (A<B, A=B, A>B) 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: (A<B) = low, (A=B) =
high, (A>B) = high. Cascading these units for
comparison of more than 4 bits is accomplished
as shown in Typical application.
