Note:

1. The input and output negative voltage ratings may be excluded if the input and output clamp ratings are observed.

3. The package thermal impedance is calculated in accordance with JESD 51.

These are stress ratings only and functional operation is not implied. Exposure to absolute maximum ratings for prolonged

periods can affect device reliability.
