These parameters are characterized but not tested.

** These parameters are design targets and are not tested.

Note 1: Data in the Typical (“Typ.”) column is at 5V, 25°C unless otherwise stated. These parameters are for design

guidance only and are not tested.

2: Measurements are taken in EXTRC mode.

3: See Figure 15-3 for loading conditions.
