Maximum ratings are those values beyond which device damage can occur. Maximum ratings applied to the device are individual stress limit
values (not normal operating conditions) and are not valid simultaneously. If these limits are exceeded, device functional operation is not implied,
damage may occur and reliability may be affected.
1. Internally limited by thermal shutdown, 150
°C min.
2. 2 layer board, 1 in2 Cu, 1 oz thickness.
3. 60−180 seconds minimum above 237
°C.
NOTE:
This device is ESD sensitive. Use standard ESD precautions when handling.
