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”

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 tothe 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.
