1. Stresses greater than those listed under ABSOLUTE MAXIMUM RATINGS may

cause permanent damage to the device. This is a stress rating only and functional Capacitance (TA = +25°C, f = 1.0MHz)

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
