Stresses exceeding Maximum Ratings may damage the device. Maximum Ratings are stress ratings only. Functional operation above the
Recommended Operating Conditions is not implied. Extended exposure to stresses above the Recommended Operating Conditions may affect
device reliability.
1. The power rating is based on a printed circuit board heat spreading capability equivalent to 2 square inches of copper connected to the GND
pins. Typical multi ? layer boards using power plane construction will provide this heat spreading ability without the need for additional
dedicated copper area. (Please consult with factory for thermal evaluation assistance).

2. Operating Characteristics are over Standard Operating Conditions unless otherwise specified.
3. The hysteresis defines the maximum level of acceptable disturbance on V CC during switching. It is recommended that the V CC source
impedance be kept below 0.25 W to ensure the switching disturbance remains below the hysteresis during select/deselect transitions. An
input capacitor may be required to help minimize the switching transient.
