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 Ratings” for extended periods may affect device reliability. Note 2: When mounted on 76.1mm×114.3mm×1.6mm glass epoxy board. Note 3: TJ=150°C. Use the IC in the range where the temperature of the chip does not exceed TJ=150°C during operation.
