| Description | The LS83A adds two 4-bit binary words (A plus B) plus the incoming carry. The binary sum appears on the sum outputs (∑1 – ∑4) and outgoing carry (C4) outputs. C0 + (A1+B1)+2(A2+B2)+4(A3+B3)+8(A4+B4) = ∑1+2∑2+4∑3+8∑4+16C4 Where: (+) = plus Due to the symmetry of the binary add function the LS83A can be used with either all inputs and outputs active HIGH (posi. |

| Title | 4-Bit Binary Adder |
| 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. |
| Features | 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 DM74LS83AN Package Number N16E Package Description 16-Lead Plastic Dual-In-Line Package (PDIP), JEDEC MS-001, 0.300 Wide Connect. |
