SN54LS283 Datasheet | Motorola Semiconductor

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 SCHOTTKY CONNECTION DIAGRAM DIP (TOP VIEW) VCC 16 B3 15 A3 14 Σ3 13 A4 12 B4 11 Σ4 10 C4 9 NOTE: The Flatpak version has the same pinouts (Connection Diagram) as the Dual In-Line Package. 16 1 J SUFFIX CERAMIC CASE 620-09 1 Σ2 2 B2 3 A2 4 Σ1 5 A1 6 B1 7 C0 8 GND 16 1 N SUFFIX PLASTIC CASE 648-08 PIN NAMES LOADING (Note a) HIGH LOW 0.5 U.L. 0.5 U.L. 0.25 U.L. 5 (2.5) U.L. 5 (2.5) U.L. 16 1 D SUFFIX SOIC CASE 751B-03 A1 - A4 B1- B4 C0 ∑1 - ∑4 C4 Operand A Inputs Operand B Inputs Carry Input Sum Outputs (Note b) Carry Output (Note b) 1.0 U.L. 1.0 U.L. 0.5 U.L. 10 U.L. 10...
