4-bit Binary Full Adder (with Fast Carry)

REJ03D0420–0200

Rev.2.00

Feb.18.2005

This improved full adder performs the addition of two 4-bit binary numbers. The sum (Σ) outputs are provided for each

bit and the resultant carry (C4) is obtained from the fourth bit. This adder features full internal look ahead across all

four bit generating the carry term in ten nanoseconds typically. This provides the system designer with partial look-

ahead performance at the economy and reduced package count of a ripple-carry implementation.
