74LS83 4-BIT BINARY FULL ADDER

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.
