Product parametric performance is indicated in the Electrical Characteristics for the listed test conditions, unless otherwise noted. Product

performance may not be indicated by the Electrical Characteristics if operated under different conditions.

23. SDO low-side switch activation time.

24. Time depends on the SDO load and pull-up resistor.
