* Stresses beyond those listed under "Absolute Maximum Ratings" may cause permanent damage
to the device. This is a stress rating only and functional operating of the device at those or any other
conditions beyond those indicated in the "Recommended Operating Conditions" section of this
specification is not implied. Exposure to absolute-maximumrated conditions for extended periods
may affect device reliability.
Notes :
1. Unless otherwise noted, all voltages are with respect to VSS.
2. Test pin must connect to VSS.
