INPUT CURRENT OF 100nA AT 18V AND 25 °C FOR HCC DEVICE . 100% TESTED FOR QUIESCENT CURRENT . 5V, 10V, AND 15V PARAMETRIC RATING . MEETS ALL REQUIREMENTS OF JEDEC TEN- TATIVE STANDARD N °13A, ”STANDARD SPE- CIFICATIONS FOR DESCRIPTION OF ”B” SERIES CMOS DEVICES” June 1989 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.
