CD4008BM/CD4008BC 4-Bit Full Adder

Features

General Description

Wide supply voltage range

3.0V to 15V

0.45 V (typ.)

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.

High noise immunity

Low power TTL

compatibility

Fan out of 2 driving 74L

or 1 driving 74LS

4 sum outputs plus parallel look-ahead carry-output

Quiescent current specified to 15V

Maximum input leakage of 1 mA at 15V (full package

temperature range)

All inputs are protected from damage due to static dis-

and GND.
