† 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.

* 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).
