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 condition beyond those indicated is not implied. Exposure to absolute
maximum rated conditions for extended periods may affect device reliability. All voltages are with respect to GND. Currents are positive
into, negative out of the specified terminal. Consult company packaging information for thermal limitations and considerations of
packages.
