13.0 DC Electrical Characteristics
PARAMETRICS DISCLAIMER
The current AC and DC specifications contained in this
document are a combination of target design specifica-
tions, limited sampled electrical data, and some charac-
terization data. Currently, this information does not rep-
resent all actual guaranteed test timing parameters.
Guaranteed specifications will be provided after full de-
vice characterization. For more specific information re-
gards DC and AC parameters, contact National Semi-
conductor.
