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.

NOTE: This device series contains ESD protection and exceeds the following tests:

Human Body Model (HBM) JESD 22−A114−B

Machine Model (MM) JESD 22−A115−A

*Which ever is less. Reverse bias protection feature valid only if (Vout − Vin) ≤ 7 V.
