74F283
4-Bit Binary Full Adder with Fast Carry
General Description
The 74F283 high-speed 4-bit binary full adder with internal
carry lookahead accepts two 4-bit binary words (A0–A3,
B0–B3) and a Carry input (C0). It generates the binary Sum
outputs (S0–S3) and the Carry output (C4) from the most
significant bit. The 74F283 will operate with either active
HIGH or active LOW operands (positive or negative logic).
