† 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 noted, voltages are reference to ground and currents are positive into, negative out of, the specified terminals. Pulsed is defined

as a less than 10% duty cycle with a maximum duration of 500 ns.
