description  
The ′F283 is a full adder that performs the addition  
of two 4-bit binary words. The sum (Σ) outputs are  
provided for each bit and the resultant carry (C4)  
output is obtained from the fourth bit.  
SN54F283 . . . FK PACKAGE  
(TOP VIEW)  
The device features full internal look-ahead  
across all four bits generating the carry term C4 in  
typically 5.7 ns. This capability provides the  
system designer with partial look-ahead  
performance at the economy and reduced  
package count of a ripple-carry implementation.

The adder logic, including the carry, is  
implemented in its true form. End-around carry  
can be accomplished without the need for logic or  
level inversion.

NC – No internal connection  
The ′F283 can be used with either all-active-high  
(positive logic) or all-active-low (negative logic)  
operands.  
The SN54F283 is characterized for operation over  
the full military temperature range of –55°C to  
125°C. The SN74F283 is characterized for  
operation from 0°C to 70°C.
