Loaddump is setup without the DUT connected to the generator per ISO 7637-1 and DIN 40839 .
Supply voltages higher than Vbb(AZ) require an external current limit for the GND pin, e.g. with a
150Ω resistor in GND connection. A resistor for the protection of the input is integrated.

Functional description LS-Pin:
With using the LS-pin it is possible to change the input turn-on and -off threshold voltage
between CMOS and half supply voltage level.
Therefore you have either to connect the LS-pin to GND ( state 1 ) or to supply voltage ( state 2 ).
If the LS-pin is not connected the input threshold voltages are automatically at CMOS level,
caused by an internal pull down to GND with typ. 800k Ω ( see circuit ).
State 1: LS-Pin to GND
State 2: LS-Pin to supply voltage
