(1)

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

Conditions is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.

(2)

These voltages represents the DC voltage + peak AC waveform measured at the terminal of the device in all conditions.

(3)

Failure to follow good anti-static ESD handling during manufacture and rework will contribute to device malfunction. Make sure the

operators handling the device are adequately grounded through the use of ground straps or alternative ESD protection.
