Note 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).
Note 2: The hysteresis defines the maximum level of acceptable disturbance on VCC during switching. It is recommended that the VCC
source impedance be kept below 0.25Ω 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.
