DESCRIPTI ON
TheHCC4063B (extended temperature range) and
HCF4063B (intermediate temperature range) are
available in 16-lead dual in-line plastic or ceramic
package and plastic micro package. The
HCC/HCF4063B is a low-power 4-bit magnitude
comparator designedfor use in computerand logic
applications that requirethecomparison oftwo4-bit
words. This logic circuit determines whether one 4bit word(Binary or BCD) is ”less than”, ”equal to”or
”greater than” a second 4-bit word. The
HCC/HCF4063B 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
comparator function to 8, 12, 16...4N bits.When a
single HCC/HCF4063B is used, the cascading inputs areconnected as follows:
(A < B) = low, (A =B) = high, (A > B) =low.
For words longer than4 bits, HCC/HCF4063B devices may be cascaded by connecting the outputs
oftheless-significant comparator tothecorresponding cascading inputs of the more-significant comparator. Cascading inputs(A < B, A = B, and A> B)
on theleastsignificant comparator areconnectedto
a low, a high,and a lowlevel, respectively.

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.
