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 MILSTD883, Method 3015.
Machine Model Method 200 V.
2. Internal thermal shutdown protection limits the die temperature to approximately 175
°
C. Proper heatsinking is required to prevent activation.
The maximum package power dissipation is:
