Additional preview pages of the 74283 datasheet.

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.

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 25 ns Two 16-bit words 45 ns s Typical power dissipation per 4-bit adder 95 mW Ordering Code: Order Number DM74LS283M DM74LS283N Package Number M16A N16E Package.
