SN74LS283 Datasheet (ON Semiconductor) - 4-Bit Binary Full Adder

SN74LS283, 4-Bit Binary Full Adder

The LS283 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 b

SN74LS283 4 Bit Binary Full Adder with Fast Carry The SN74LS283 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 LS283 operates with either active HIGH or active LOW operands (positive or negative logic).
