Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability.
ELECTRICAL CHARACTERISTICS
(VDD = +2.7V to +5.5V, TA = -40°C to +125°C. Typical values are at VDD = +3.3V and TA = +25°C, unless otherwise noted.) (Note 1)

Note 1:
Specifications over temperature are guaranteed by design. Parts are 100% production tested at 10°C below the tempera- ture threshold.
