In order to ensure that the level of the power supply voltage is correct, an external resistor must be connected
between R-EXT and GND.
GND
OUT0 to OUT15 = On when Dn = H; OUT0 to OUT15 = Off when Dn = L.
Please take care when wiring the output terminals, the power supply terminal and the GND terminals.
