They are for initial design estimations only, and assume optimum manufacturing and application conditions. Performance may vary for individual units, within the specifi ed maximum and minimum limits. 3 In these tests, the vector
X
is intended to represent positive and negative fi elds suffi cient to swing the output driver between fully OFF and saturated (ON), respectively. It is NOT intended to indicate a range of linear operation. 4 Noise specifi cation includes both digital and analog noise.
