ABSOLUTE MAXIMUM RATINGS
Storage Temperature:
Ambient Temperature Under Bias:
Supply Voltage to AV
Stresses above those listed under Absolute Maximum Rat-
ings may cause permanent device failure. Functionality at or
above these limits is not implied. Exposure to absolute maxi-
mum ratings for extended periods may affect device reliability.
