54F283 adders equivalent, 4-bit binary full adders.
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 perfo.
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 features full internal look-ahead across all.
