Tabl e 14 lists the guaranteed maximum and minimum specifications for the voltage and temperature ranges: 4.75V to 5 .25V and -40°C
TA 85°C, 3.0V to 3.6V and -40°C TA 85°C, or 2.4V to 3.0V and -40°C TA 85°C, respectively. Typical parameters apply to
5V, 3.3V, or 2.7V at 25°C and are for design guidance only.

TAAmbient Temperature -40 +85 oC
TJJunction Temperature -40 +100 oCThe temperature rise from ambient
to junction is package specific. See
Table 40 on page 38. The user must
limit the power consumption to
comply with this requirement.
