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).
