†
Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device. These are stress ratings only, and
functional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is not
implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
‡
Unless otherwise indicated, voltages are reference to ground and currents are positive into and negative out of the specified terminals.
w In normal operation V
CC
is powered through a current limiting resistor. Absolute maximum of 12 V applies when V
CC
is driven from a low
impedance source such that I
CC
does not exceed 30 mA (which includes gate drive current requirement).
