Z = high impedance, potential depends on external circuit
Status signal valid after the time delay shown in the timing diagrams
Parallel switching of channel 1 and 2 (also channel 3 and 4) is easily possible by connecting the inputs and
outputs in parallel (see truth table). If switching channel 1 to 4 in parallel, the status outputs ST1/2 and ST3/4
have to be configured as a 'Wired OR' function with a single pull-up resistor.

External R_GND optional; two resistors R_GND1, R_GND2 = 150 Ω or a single resistor R_GND = 75 Ω for reverse
battery protection up to the max. operating voltage.
