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
micro package. The HCC/HCF4585B is a 4-bit mag-
nitude 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. 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.

Stresses above those listed under "Absolute Maximum Ratings" may cause permanent damage to the device. This is a stress
rating only and functional operation of the device at these or any other conditions above those indicated in the operational sections
of this specification is not implied. Exposure to absolute maximum rating conditions for external periods may affect device reliability.
