†
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 c onditions” is not
implied. Exposure to absolute--m aximum--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 P ackaging Section of the Databook
for thermal limitations and considerations of packages.
