CD4008BM CD4008BC 4-Bit Full Adder February 1988 CD4008BM CD4008BC 4-Bit Full Adder General Description The CD4008B 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’’ bit to permit high-speed operation in arithmetic sections using several CD4008B’s CD4008B 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 CD4008B outputs include the four sum bits S1 and S4 in addition to the high-speed ‘‘parallel-carry-out’’ which may be utilized at a succeeding CD4008B section All inputs are protected from damage due to static discharge by diode clamps to VDD and GND Features Y Y Y Y Y Y Wide supply voltage range 3 0V to 15V High noise immunity 0 45 VCC (typ ) Low power TTL Fan out of 2 driving 74L compatibility or 1 driving 74LS 4 sum outputs plus parallel look-ahead carry-output
