1. Maximum Ratings are those values beyond which damage to the device may occur. Exposure to these conditions or conditions beyond those
indicated may adversely affect device reliability. Functional operation under absolute maximum−rated conditions is not implied. Functional
operation should be restricted to the Recommended Operating Conditions.
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.
