IMPORTANT NOTES AND CAVEATS:

️· "Type" Designations: Pay close attention to the "Type" (A, B, C, D) designations for each electrical characteristic. This indicates the level of testing and reliability associated with that value.
️· Supply Voltage Dependence: Many characteristics, especially those related to the LIN bus driver voltages (e.g., V_HiSUP, V_LoSUP), *depend on the supply voltage (VS)*. The provided values are for specific supply voltages and will change with different voltages.
️· Refer to the Full Datasheet: This is a highly condensed summary. ALWAYS refer to the full ATA6662 datasheet for complete details, conditions, and applicable diagrams. There are many more parameters and conditions not covered here.
️· Safety and Application Notes: Datasheets often contain important safety information and application notes. Be sure to read those sections.
