NOTES:

1. Permanent device damage may occur if ABSOLUTE MAXIMUM RATINGS are exceeded. This is a stress rating only and functional operation is not

implied at conditions other than those detailed in the operational sections of this data sheet. Exposure to ABSOLUTE MAXIMUM RATING conditions

for extended periods may affect device reliability.

2. Either voltage limit or current limit is sufficient to protect input.

3. All DC and AC electrical characteristics are specified over the operating termperature range.
