For hardware version 1.2: Do not connect either IN_2 or IN_3 directly to a low resistance
supply voltage (e.g. directly to any power supply voltage). As the output transistors connected
in parallel might briefly switch-on during power-up they might be damaged / destroyed if the
current through the transistors to ground exceeds 100mA.
