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).
