Notes: 1. Absolute maximum ratings are those values beyond which the device could be permanently damaged.

Absolute maximum ratings are stress ratings only and functional device operation is not implied.

2. Shorting output to V+ will adversely affect reliability.

3. Shorting output to V- will adversely affect reliability
