Note 1:
Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Operating Ratings indicate conditions for which the device is
intended to be functional, but specific performance is not guaranteed. For guaranteed specifications and the test conditions, see Electrical Characteristics.
Note 2:
The human body model is a 100 pF capacitor discharged through a 1.5 k
resistor into each pin.
Note 3:
VCC provides self bias for the internal gate drive and control circuits. Device thermal limitations limit external loading.
Note 4:
Typical specifications represent the most likely parametric norm at 25°C operation.
