Description
The SN74LS83N is a high-speed 4-Bit binary Full Adder with internalcarry lookahead. It accepts two 4-bit binary words (A1– A4, B1– B4) and aCarry Input (C0). It generates the binary Sum outputs ∑1–∑4) and the Carry Output (C4) from the most significant bit.
The SN74LS83N operates with eitheractive HIGH or active LOW operands (positive or negative logic). TheSN54 / 74LS283 is recommended for new designs since it is identical infunction with this device and features standard corner power pins.
