DESCRIPTION

The HCC4585B (extended temperature range) and

HCF4585B (intermediate temperature range) are

monolithic integrated circuits, available in 16-lead

dual in-line plastic or ceramic package, and plastic

micropackage. TheHCC/HCF4585B isa4-bitmag-

nitudecomparator designed for usein computer and

logicapplications that require thecomparison 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. The

HCC/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 systems designers to expand the com-

parator function to 8, 12, 16 ... 4 N bits. When a

single HCC/HCF4585B is used, the cascading in-

puts 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.
