DESCRIPTION The HCF4008B is a monolithic integrated circuit fabricated in Metal Oxide Semiconductor technology available in DIP and SOP packages. The HCF4008B consists 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 HCF4008B's. HCF4008B inputs include the four sum bits, S1 to S4. In addition to the high speed "parallel carry out" which may be utilized at a succeeding HCF4008B section.
