VDD1
GND1
Supply Voltage for Isolator Side 1 (2.7 V to 5.5 V).
Ground 1. Ground reference for Isolator Side 1. Pin 2 and Pin 8 are internally connected, and connecting both to GND1 is
recommended.

DISABLE
Input Disable. Disables the isolator inputs and halts the dc refresh circuits. Outputs take on the logic state
determined by CTRL2.

CTRL2
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, VOC, and
VOD outputs are high when CTRL2 is high or disconnected and VDD1 is off. VOA, VOB, VOC, and VOD outputs are low when
CTRL2 is low and VDD1 is off. When VDD1 power is on, this pin has no effect.
