General 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.

The device

Key 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. The ′F283 can be used with either all-active-high (positive logic) or all-active-low (negativ.
