These parameters are characterized but not tested.

† Data in “Typ” column is at 3.0V, 25°C unless otherwise stated. These parameters are for design guidance

only and are not tested.

Note 1:

To ensure these voltage tolerances, VDD and VSS must be capacitively decoupled as close to the device as

possible. 0.1

F and 0.01 F values in parallel are recommended.
