4-Bit Binary Adders with Fast Carry
General Description
Features
Y
Full-carry look-ahead across the four bits
These full adders perform the addition of two 4-bit binary
numbers. The sum (R) 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.
Y
Systems achieve partial look-ahead performance with
the economy of ripple carry

Typical add times
Two 8-bit words 25 ns
Two 16-bit words 45 ns

Typical power dissipation per 4-bit adder 95 mW
Alternate Military/Aerospace device (5avail-
able. Contact a National Semiconduffice/
Distributor for specifications.
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.

Absolute Maximum Ratings (Note)
If Military/Aerospace specified devices are required,
please contact the National Semiconductor Sales
Office/Distributors for availability and specifications.
Note: The ‘‘Absolute Maximum Ratings’’ are those values
beyond which the safety of the device cannot be guaran-
teed. The device should not be operated at these limits. The
parametric values defined in the ‘‘Electrical Characteristics’’
table are not guaranteed at the absolute maximum ratings.
The ‘‘Recommended Operating Conditions’’ table will define
the conditions for actual device operation.
