All parameters are guaranteed in the temperature range -40 to 150 °C (unless otherwise specified); the device is

still operative and functional at higher temperatures (up to 165 °C).

Note:

•

Parameters limits at higher temperatures than 150 °C may change with respect to what is specified as per

the standard temperature range.

•

Device functionality at high temperature is guaranteed by characterization.
