† _{Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device. This is a stress rating only, and}
functional operation of the device at these or any other conditions beyond those indicated in the “recommended operating conditions” section of
this specification is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
NOTES: 1. The input and output negative-voltage ratings may be exceeded if the input and output clamp-current ratings are observed.
2. The package thermal impedance is calculated in accordance with EIA/JEDEC Std JESD51, except for through-hole packages,
which use a trace length of zero.
