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

Ground 1. Ground reference for Isolator Side 1. Pin 2 and Pin 8 are internally connected, and connecting both to GND1 is
recommended.
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, VOB, and VOC
outputs are high when CTRL2 is high or disconnected and VDD1 is off. VOA, VOB, and VOC outputs are low when CTRL2 is
low and VDD1 is off. When VDD1 power is on, this pin has no effect.
