DM74S283 - 4-Bit Binary Adder with Fast Carry

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.

Features

DM74S283 4-Bit Binary Adder with Fast Carry August 1986 Revised May 2000 DM74S283 4-Bit Binary Adder 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 lookahead 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 accomplished without the need for logic or level inversion.
