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 dis-
charge by diode clamps to V
DD
and GND.
