(1) 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.
(2) These devices are sensitive to electrostatic discharge; follow proper device handling procedures.
(3) All voltages are with respect to GND unless otherwise noted. Currents are positive into, negative out of the specified terminal. Consult
Packaging Section of the Data book for thermal limitations and considerations of packages.
