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).
