* 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 14-3 for loading conditions.
