LIN 2.1/SAE J2602 transceiver
8. Limiting values
[1] Equivalent to discharging a 150 pF capacitor through a 330 resistor; verified by an external test house.
[2] Equivalent to discharging a 100 pF capacitor through a 1.5 k resistor.
[3] Equivalent to discharging a 200 pF capacitor through a 10 resistor and a 0.75 H coil.
[4] Junction temperature in accordance with IEC 60747-1. An alternative definition is: T
j
=T

+P R
th(j-a)
, where R
th(j-a)
is a fixed value.
The rating for T

limits the allowable combinations of power dissipation (P) and ambient temperature (T
amb
).
