PRELIMINARY

ABSOLUTE MAXIMUM RATINGS

Case Temperature under Bias . . . – 65°C to +110°C

Storage Temperature . . . . . . . . . . – 65°C to +150°C

Voltage on any pin

with respect to ground . . . . . . – 0.5 V to Vcc +2.6 V

Supply voltage with

respect to VSS . . . . . . . . . . . . . . – 0.5 V to +4.6 V

Stresses above those listed under Absolute Maximum Ratings

may cause permanent device failure. Functionality at or above

these limits is not implied. Exposure to Absolute Maximum

Ratings for extended periods may affect device reliability.

OPERATING RANGES

Commercial (C) Devices

TCASE . . . . . . . . . . . . . . . . . . . . . . . . . . . 0°C to 85°C

VCC . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 3.3 V ±0.3 V

Operating Ranges define those limits between which the func-

tionality of the device is guaranteed.
