Precaution for using more than one inverter
If more than one inverter uses a common input (such as a switch), and their power-on timing is dif-
ferent, a sneak current will flow in the circuit as shown below. This may cause the inverters to falsely
recognize the input signal is ON even if it is OFF. If this occurs, insert a diode (rating: 50 V/0.1 A) in
the position shown in the diagram or redesign the circuit to use an external power supply to prevent
sneak current.
