FEATURES Back to Top
Full-Carry Look-Ahead Across the Four Bits● Systems Achieve Partial Look-Ahead Performance with the Economy of Ripple Carry● Supply Voltage and Ground on Corner Pins to Simplify P-C Board Layout●
DESCRIPTION Back to Top
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 ( ) outputs are provided for each bit
and the resultant carry (C4) is obtained from the fourth bit. These adders feature full internal look-ahead across all four bits
generating the carry term in ten nanoseconds, typically, for the '283 and 'LS283, and 7.5 nanoseconds for the 'S283. 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.
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.
