Description
CD4008BMS 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” but to permit
high-speed operation in arithmetic sections using several
CD4008BMS’s.
CD4008BMS 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. CD4008BMS 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 CD4008BMS
section.
The CD4008BMS is supplied in these 16-lead outline pack-
ages:
