1) Not subject to production test, specified by design

BUS_CNT =(Vth_dom + Vth rec)/2

HYS = Vth_rec - Vth_dom

4) Delay time specified for a load of 10 k

Ω / 20 pF on the INH output

5) Bus load concerning LIN Spec 2.2A:

Load 1 = 1 nF / 1 kΩ =

BUS / RL

Load 2 = 6.8 nF / 660 Ω =

BUS / RL

Load 3 = 10 nF / 500 Ω =

BUS / RL
