Notes:

1. Stress greater than those listed under ABSOLUTE MAXIMUM RATINGS may cause permanent

damage to the device. This is a stress rating only and functional operation of the device at these or any

other conditions above those indicated in the operational sections of this specification is not implied.

Exposure to absolute maximum rating conditions for extended periods may affect reliability.
