DM74S283 carry equivalent, 4-bit binary adder with fast carry.
s Full-carry look-ahead across the four bits s Systems achieve partial look-ahead performance with the economy of ripple carry s Typical add times Two 8-bit words 15 ns T.
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 p.
