DESCRIPTION
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
to be added, A1 to A4 and B1 to B4, in addition to the
”Carry In” bit from a previous section.
HCC/HCF4008B outputs include the four sum bits,
S1 to S4. In addition to the high speed ”parallel-carry-
out” which may be utilized at a succeeding
HCC/HCF4008B section.
