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. Maximum electrical ratings are defined as those values beyond which damage to the device may occur at TA = 25ยฐC.
2. According to JEDEC standard JESD22โˆ’A108B.
3. This device series contains ESD protection and exceeds the following tests:
Human Body Model (HBM) per JEDEC standard: JESD22โˆ’A114.
Machine Model (MM) per JEDEC standard: JESD22โˆ’A115.
4. Latchup current maximum rating per JEDEC standard: JESD78.
