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
State 1: LS-Pin to GND
