Stresses exceeding Maximum Ratings may damage the device. Maximum Ratings are stress ratings only. Functional operation above the
Recommended Operating Conditions is not implied. Extended exposure to stresses above the Recommended Operating Conditions may affect
device reliability.
1. This device series contains ESD protection and exceeds the following tests:
Human Body Model 2000 V per Mil−Std−883, Method 3015.
Machine Model Method 200 V.
2. This device contains latchup protection and exceeds 100 mA per JEDEC Standard JESD78.
