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.

A. This device series contains ESD protection and exceeds the following tests:

Pins 1−3: Human Body Model 2000 V per MIL−STD−883, Method 3015.

Machine Model Method 400 V.

Pin 5: Human Body Model 1000 V per MIL−STD−883, Method 3015.

Machine Model Method 400 V.

Pin 5 is connected to the power switch and start−up circuits, and is rated only to the max voltage of the part, or 700 V.

B. This device contains Latch−up protection and exceeds

$100 mA per JEDEC Standard JESD78.
