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 (A
0
鈥揂
3
,
B
0
鈥揃
3
) and a Carry input (C
0
). It generates the binary Sum
outputs (S
0
鈥揝
3
) and the Carry output (C
4
) from the most
significant bit. The 74F283 will operate with either active
HIGH or active LOW operands (positive or negative logic).
