Storage Temperature
Ambient Temperature
Supply Voltage
Referenced to V
DC Voltage applied to any
Pin Referenced to V
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.
