† Stresses beyond those listed under "absolute maximum ratings" may cause permanent damage to the device. These are stress ratings only and
functional operation of the device at these or any other conditions beyond those indicated under "recommended operating conditions" is not
implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
NOTE 1: The input voltage ratings may be exceeded provided the input current ratings are observed.


Description

The SN54F283 is a full adder that performs the addition of two 4-bit binary words. The sum (S) outputs are provided for each bit and the resultant carry (C4) output is obtained from the fourth bit.

The SN54F283 features full internal look-ahead across all four bits generating the carry term C4 in typically 5.7 ns. SN54F283 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, SN54F283 is implemented in its true form. End-around carry can be accomplished without the need for logic or level inversion.

The SN54F283 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.
