These parameters are characterized but not tested.

** These parameters are design targets and are not tested. No characterization data available at this time.

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 10-1 for loading conditions.
