FAST AND LS TTL DATA
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, 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 ac-
tive HIGH or active LOW operands (positive or negative logic).
