Stresses above those l isted under ” Absolute Maximum Ratings” may cause permanent damage to the devi ce. This is a stress
rati ngs only and functional operation of the device at these or any other conditions above those indicated in the operating con-
ditions of this specificati on is not implied. Exposure to absolute maximum rating conditions for extended periods may affect devi ce
reliabili ty.
