[1] This parameter is tested by applying a square wave signal to the LIN. The minimum slew rate for the LIN rising and falling edges is 50V/us
[2] See Figure 4– LIN timing diagram
[3] Standard loads for duty cycle measurements are 1K/1nF, 660/6.8nF, 500/10nF, internal master termination disabled
[4] in accordance to SAE J2602, see Figure 5
[5] for supply voltage ranges Vs=5…7V and Vs=18…27V parametric deviations are possible
