ABSOLUTE MAXIMUM RATINGS

Storage Temperature:

–65

°C to +150°C

. . . . . . . . . . .

Ambient Temperature Under Bias:

°C to +70°C

. . . .

Supply Voltage to AVSS or DVSS

(AVDD, DVDD):

–0.3 V to +6 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.

OPERATING RANGES

Commercial (C) Devices

Temperature (TA):

°C to +70°C

. . . . . . . . . . . . . . . .

Supply Voltages (AVDD, DVDD):

+5 V

± 5%

. . . . . . . . .

All inputs within the range:

AVSS–0.5 V

≤ VIN ≤ AVDD + 0.5 V, or

DVSS–0.5 V

≤ VIN ≤ DVDD +0.5 V

Operating ranges define those limits between which the func-

tionality of the device is guaranteed.
