Electrical Specification Footnotes
1. This spec will be guaranteed and verified in production samples, but will not be measured in produc-
tion.
2. This spec will be guaranteed and verified in production samples, but will be measured in production
only at DC.
3. This spec will be measured in production at the limits of the specified operating temperature.
4. This spec defines a nominal relationship rather than a measured parameter. Correct circuit operation
will be verified with other specs that use this nominal relationship as a reference.
