DESCRIPTI ON
TheHCC4585B (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 foruseincomputer and
logicapplications that require thecomparison of two
4-bit words. This logic circuit determines whether
one 4-bit word(BinaryorBCD)is”less than”, ”equal
to”, or ”greater than” a second 4-bit word. The
HCC/HCF4585B has eight comparing inputs (A3,
B3,throughA0, B0),threeoutputs(A<B, A= B, A>
B) and three cascadinginputs (A < B, A = B, A > B)
that permit systems designers to expand the com­parator function to 8, 12, 16 ... 4 N bits. When a
single HCC/HCF4585B is used, the cascading in­puts are connected as follows : (A < B) = low,
(A =B) =high, (A> B)= high.Cascadingthese units
for comparison of more than 4 bits is accomplished
as shownin typicalapplication.
