DESCRIPTION
The HCC4063B (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 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/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...4 N bits. When a
single HCC/HCF4063B is used, the cascading in-
puts are connected as follows :
(A < B) = low, (A = B) = high, (A > B) = low.
For words longer than 4 bits, HCC/HCF4063B de-
vices may be cascaded by connecting the outputs
of the less-significant comparator to the correspond-
ing cascading inputs of the more-significant com-
parator. Cascading inputs (A < B, A = B, and A > B)
on the least significant comparator are connected to
a low, a high, and a low level, respectively.
