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.
