This parameter is has been verified in production samples, but is not measured in production.
This parameter is has been verified in production samples, but is measured in production only at DC.
This parameter is measured in production at the limits of the specified operating temperature.
This parameter defines a nominal relationship rather than a measured parameter. Correct circuit operation is verified with other specs
