Nomenclature Used in This Document
Some terms and names used in this data sheet deviate from those referred to in the LIN specifications. Equivalent
values are shown below.
NOTICE: Stresses above those listed under “Maximum Ratings” may cause permanent damage to the device. This
is a stress rating only and functional operation of the device at those or any other conditions above those indicated in
the operational listings of this specification is not implied. Exposure to maximum rating conditions for extended periods
may affect device reliability.
