WARNING: 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.

WARNING: Electrostatic Discharge (ESD) can damage this device. Proper procedures must be followed to avoid ESD when

handling this device.
