(1)
Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. These are stress ratings
only, which do not imply functional operation of the device at these or any other conditions beyond those indicated under Recommended
Operating Conditions. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
(2)
In normal operation, VCC is powered through a current-limiting resistor. Absolute maximum of 12 V applies when VCC is driven from a
low impedance source, such that ICC does not exceed 30 mA (which includes the gate drive current requirement). The resistor must be
sized so that the VCC voltage, under operating conditions, is below 12 V but above the turnoff threshold.
(3)
Return the minimum (lesser) value of the two.
