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. TL=Lead temperature at 3/8 " (9.5mm) from body.
3. Valid provided that leads are kept at ambient temperature at a distance of 10 mm from case.
