Logic Input A.
Logic Input B.
Logic Output C.
Logic Output D.
Default Output Control. Controls the logic state the outputs assume when the input power is off. VOC and VOD outputs
are high when CTRL1 is high or disconnected and VDD2 is off. VOC and VOD outputs are low when CTRL1 is low and VDD2 is
off. When VDD2 power is on, this pin has no effect.

Ground 2. Ground reference for Isolator Side 2. Pin 9 and Pin 15 are internally connected, and connecting both to GND2 is
recommended.
Default Output Control. Controls the logic state the outputs assume when the input power is off. VOA and VOB outputs
are high when CTRL2 is high or disconnected and VDD1 is off. VOA and VOB outputs are low when CTRL2 is low and VDD1 is
off. When VDD1 power is on, this pin has no effect.
