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.

The data sheet limits are not guaranteed if the device is operated beyond the operating ratings.

3.

Thermal performance assumes the use of a 4-layer PCB. Exposed pad must be soldered (or equivalent) to the device’s most negative potential

on the PCB
