4-Bit Binary Adders with Fast Carry
General Description
These full adders perform the addition of two 4-bit binary
numbers The sum ( ) outputs are provided for each bit and
the resultant carry (C4) is obtained from the fourth bit
These adders feature full internal look ahead across all four
bits This provides the system designer with partial look-
ahead performance at the economy and reduced package
count of a ripple-carry implementation
The adder logic including the carry is implemented in its
true form meaning that the end-around carry can be accom-
plished without the need for logic or level inversion
