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

2Typical data is at TA = 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.
