All parameters are guaranteed over the virtual junction temperature range by design. Products are 100 % tested at 125 C ambient
temperature (wafer level pretesting), and 100 % tested at 25 C ambient temperature (final testing). Both pretesting and final testing use
correlated test conditions to cover the specified temperature and power supply voltage range.
