*) Type means: A = 100% tested, B = 100% correlation tested, C = Characterized on samples, D = Design parameter
No. Parameters
Input leakage current at the
receiver including pull-up
resistor as specified
Leakage current LIN
recessive
Leakage current at ground
loss
Control unit disconnected
from ground
Loss of local ground must
not affect communication in
the residual network
Node has to sustain the
current that can flow under
this condition. Bus must
remain operational under
this condition
Symmetry of receiver
propagation delay rising
edge minus falling edge
