²Stresses beyond those listed under ªabsolute maximum ratingsº 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 ªrecommended operating conditionsº is not implied. Exposure to absolute-maximum-rated conditions for

extended periods may affect device reliability. NOTES: 1. Voltage values are with respect DVSS.

2.Maximum supplied voltage should not exceed 6 V.

3.Voltage values are with respect to AVSS.
