54283 DM74283
4-Bit Binary Full Adder (with Fast Carry)
General Description
The ’283 high speed 4-bit binary full adders with internal
carry lookahead accept two 4-bit binary words (A0–A3 B0–
B3) and a Carry input (C0) They generate the binary Sum
outputs (S0–S3) and the Carry output (C4) from the most
significant bit They operate with either active HIGH or ac-
tive LOW operands (positive or negative logic)
