¹Negative current is deﬁned as conventional current coming out of (sourced from) the speciﬁed device terminal.

²Typical data is at T_A= 25°C. They are for initial design estimations only, and assume optimum manufacturing and application

conditions. Performance may vary for individual units, within the speciﬁed maximum and minimum limits.

³In these tests, the vector X is intended to represent positive and negative ﬁelds sufﬁcient to swing the output driver between fully OFF

and saturated (ON), respectively. It is NOT intended to indicate a range of linear operation.

⁴Noise speciﬁcation includes both digital and analog noise.
