Sum (Σ) outputs are provided for each bit and a
resultant carry (C4) is obtained from the fourth bit.
This adder features full internal look ahead across
all four bits. A 4 x n binary adder is easily built up
by cascading without any additional logic.
All inputs are equipped with protection circuits
against static discharge and transient excess
voltage.
