1) No measurement in mass production, parameter is guaranteed by design and/or quality observation.
2) Valid for the dice. Note that the package and the temperature version causes additional restrictions.
3) Over lifetime and valid for the dice. Use the calculation sheet IDT Temperature Profile Calculation Sheet for temperature stress calculation. Note that
the package and the temperature version causes additional restrictions.
