The '283 and 'LS283 adders are electrically and functionally identical to the '83A and 'LS83A, respectively; only the arrangement of the terminals has been changed. The 'S283 high performance versions are also functionally identical. These improved full adders perform the addition of two 4-bit binary words. The sum ( 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. Series 54, Series 54LS, and Series 54S circuits are characterized for operation over the full temperature range of -55°C to 125°C. Series 74, Series 74LS, and Series 74S circuits are characterized for 0°C to 70°C operation.
