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.  All voltage values are with respect to GND.
2.  Long-term storage or operation above 70癈 could cause package yellowing that will lower the sensitivity to wavelengths < 500nm.
