26. Electrical Characteristics
All DC/AC characteristics contained in this datasheet are based on simulations and character-
ization of similar devices in the same process and design methods. These values are
preliminary representing design targets, and will be updated after characterization of actual
automotive silicon data.

ditions beyond those indicated in the operational
sections of this specification is not implied. Expo-
sure to absolute maximum rating conditions for
extended periods may affect device reliability.
