SN54LS283 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 Example: C0 logic levels Act.

SN54/74LS283 4-BIT BINARY FULL ADDER WITH FAST CARRY The SN54 / 74LS283 is a high-speed 4-Bit Binary Full Adder with internal carry lookahead. It accepts two 4-bit binary words (A1 A4, B 1 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). 4-BIT BINARY FULL ADDER WITH FAST CARRY LOW POWER SCHOT.
