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.
