Notes:

1. For conditions shown as Max. or Min., use appropriate value specified under Electrical Characteristics for the applicable device type.

2. Typical values are at VCC = 3.3V, +25°C ambient and maximum loading.

3. Unused Control Inputs must be held HIGH or LOW to prevent them from floating.
