[1] Propagation delays are not relevant for LIN protocol transmission, value only information parameter
[2] No production test, guaranteed by design and qualification
[3] See Figure 2 - Input / Output timing
[4] See Figure 8 - Slope time and slew rate calculation
[5] See Figure 3 – Receiver debouncing a and propagation delay
[6] In accordance to LIN Physical Layer Specification 1.3
[7] In accordance to LIN Physical Layer Specification 2.0
[8] See Figure 9 - Duty cycle calculation in accordance to LIN 2.0
[9] This parameter is tested by applying a wave signal to the bus. The minimum slew rate for the bus rising and falling edge is
50V/µs
