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). GUARANTEED OPERATING RANGES Symbol Parameter Min Typ Ma.
