4-Bit Binary Adder with Fast Carry

General Description

Features

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.

■ Full-carry look-ahead across the four bits

■ 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

The adder logic, including the carry, is implemented in its

true form meaning that the end-around carry can be

accomplished without the need for logic or level inversion.
