Stresses exceeding those listed in the Maximum Ratings table may damage the device. If any of these limits are exceeded, device functionality

should not be assumed, damage may occur and reliability may be affected.

1. 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)
