FOOTNOTES:
1 This spec is guaranteed, has been verified in production samples, but is not measured in production.
2 This spec is guaranteed, has been verified in production samples, but is measured in production only at DC.
3 This spec is 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 is verified with other specs that use
this nominal relationship as a reference
