NOTE 1 – Typical data is at TA = 25°C and is for design information only.

NOTE 2 – Negative current is defined as coming out of (sourcing) the output.

* This test requires 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.
