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.
2. This device series contains ESD protection and exceeds the following tests:
Human Body Model (HBM) $ 2.0 kV per JEDEC standard: JESD22?A114.
Machine Model (MM) $ 200 V per JEDEC standard: JESD22?A115.
3. Latchup Current Maximum Rating: $ 150 mA per JEDEC standard: JESD78.
4. Moisture Sensitivity Level (MSL): 1 per IPC/JEDEC standard: J?STD?020A.
