1. Operating Characteristics are over Standard Operating Conditions unless otherwise specified.

2. Hysteresis level defines the maximum level of acceptable noise on VCC during switching. Excessive parasitic inductance on VCC board traces

to the CMPWR025 may require an input capacitor to adequately filter the supply noise to below the hysteresis level. This will ensure that

precise switching occurs between VCC1 and VCC2 supply inputs.

3. This is the time, after the select/deselect threshold is reached, for the switches to react.
