ABSOLUTE MAXIMUM RATINGS
Storage Temperature
Ambient Temperature
Under Bias
Supply Voltage to AVSS or VSSB
(AVDD, VDD, VDDB)
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.

Supply Voltages
(AVDD, VDD, VDDB)
All Inputs within the Range:
AVSS – 0.5 V
or VSS – 0.5 V
or VSSB – 0.5 V
Operating ranges define those limits between which the func-
tionality of the device is guaranteed.
