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)
