The HCC4008B (extended temperature range) and

HCF4008B (intermediate temperature range) are

monolithic integrated circuits, available in 16-lead

dual in-line plastic or ceramic package and plastic

micropackage.

The HCC/HCF4008B types consist of four full adder

stages with fast look ahead carry provision from

stage to stage. Circuitry is included to provide a fast

”parallel-carry-out” to permit high-speed operation

in arithmetic sections using several HCC/HCF

4008B’s.

HCC/HCF4008B inputs include the four sets of bits

”Carry

In”

bit

from

a

previous

section.

HCC/HCF4008B outputs include the four sum bits,

out” which may be utilized at a succeeding

HCC/HCF4008B section.
