Overview: 4-BIT BINARY FULL ADDER WITH FAST CARRY The SN54 / 74LS83A is a high-speed 4-Bit binary Full Adder with internal carry lookahead. It accepts two 4-bit binary words (A1 – A4, B1 – B4) and a Carry Input (C0). It generates the binary Sum outputs ∑1 – ∑4) and the Carry Output (C4) from the most significant bit. The LS83A operates with either active HIGH or active LOW operands (positive or negative logic).
This datasheet includes multiple variants, all published together in a single manufacturer document.

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: (+)
