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. Refer to ELECTRICAL CHARACTERISTIS and APPLICATION INFORMATION for Safe Operating Area.

2. This device series incorporates ESD protection and is tested by the following methods:

ESD Human Body Model tested per AEC−Q100−002 (EIA/JESD22−A114)

ESD Machine Model tested per AEC−Q100−003 (EIA/JESD22−A115)

Latchup Current Maximum Rating tested per JEDEC standard: JESD78.
