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. 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. Latch up capability (85C) 100 mA DC with trigger voltage.
