[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 5 – LIN timing diagram
[3] Standard loads for duty cycle measurements are 1K/1nF, 660/6.8nF, 500/10nF
[4] Not valid for the SAE J2602 version (optimized for 10.4kBd operation) of the MLX80020 xA
[5] In accordance to SAE J2602, only for device version MLX80020 xB
