Latch−up Current Maximum Rating per JEDEC Standard: JESD78 − "100 mA
Moisture Sensitivity (Note 5) − 1
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.
3. 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.
4. The maximum package power dissipation limit must not be exceeded.
5. Moisture Sensitivity Level (MSL): 1 per IPC/JEDEC standard: J−STD−020A.
