(1)

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.

(2)

All voltages are with respect to GND if not specified. Currents are positive into, negative out of the specified terminal. Consult Packaging

Section of the data book for thermal limitations and considerations of packages.
