† _{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.
NOTES: 1. This value is limited to 4.6 V maximum.
2. This value is limited to 6 V maximum.
3. The package thermal impedance is calculated in accordance with JESD 51-7.
