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. The
HCC/HCF4585B
isa4-bitmag-
nitudecomparator designed foruseincomputer and
logicapplications that require thecomparison oftwo
4-bit words. This logic circuit determines whether
one 4-bit word(Binary orBCD) 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), threeoutputs (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.Cascadingthese units
for comparison of more than 4 bits is accomplished
as shownin typical application.
