DESCRIPTION
TheHCC4008B (extended temperaturerange)and
HCF4008B (intermediate temperature range) are
monolithic integrated circuits, available in 16-lead
dual in-line plastic or ceramic package and plastic
micropackage.
TheHCC/HCF4008Btypesconsist offourfulladder
stages with fast look ahead carry provision from
stagetostage.Circuitry isincluded toprovidea fast
”parallel-carry-out” to permit high-speed operation
in arithmetic sections using several HCC/HCF
4008B’s.
HCC/HCF4008B inputsincludethe foursets of bits
tobe added,A1to A4andB1toB4, in addition to the
”Carry In” bit from a previous section.
HCC/HCF4008B outputs include the four sum bits,
S1toS4.Inaddition to thehighspeed”parallel-carryout” which may be utilized at a succeeding
HCC/HCF4008B section.
