Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. These are stress ratings
only, which do not imply functional operation of the device at these or any other conditions beyond those indicated under Recommended
Operating Conditions. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
(2)
All voltages are with respect to GND. Currents are positive into, negative out of the specified pin. These ratings apply over the operating
ambient temperature ranges unless otherwise noted.
(3)
Do not drive with low impedance voltage source.
