Fairchild Semiconductor 

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).
