1. All specifications are subject to change without notice.
2. Unless otherwise noted, T
3. Stresses above those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only; the functional operation of
the device at these or any other conditions above those indicated in the operational sections of this specification is not impli ed. Exposure to absolute maximum rating condi-
tions for extended periods may affect device reliability.
