7. Propagation delays are not relevant for LIN protocol transmission, value only information parameter.
8. No production test, guaranteed by design and qualification.
9. See Figure 2 − Input/Output Timing.
10. See Figure 8 − Slope Time Calculation.
11. See Figure 3 − Receiver Debouncing.
12. In accordance to LIN physical layer specification 1.3.
13. In accordance to LIN physical layer specification 2.0.
14. This parameter is tested by applying a square wave to the bus. The minimum slew rate for the bus rising and falling edges is 50 V/ms.
