‡ 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.
§ All voltages are with respect to ground. Currents are positive into and negative out of the specified terminals. Consult the Packaging Section of
the Databook for thermal limitations and considerations of the package.
