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 GND
recommended.
Logic Input A.
Logic Input B.
Logic Input C.
Logic Input D.
Input Disable. Disables the isolator inputs and halts the dc refresh circuits. Outputs take on the logic state determined
by CTRL.
Ground 1. Ground reference for Isolator Side 1. Pin 2 and Pin 8 are internally connected, and connecting both to GND
recommended.
Ground 2. Ground reference for Isolator Side 2. Pin 9 and Pin 15 are internally connected, and connecting both to GND
recommended.
Default Output Control. Controls the logic state the outputs assume when the input power is off. V
outputs are high when CTRL is high or disconnected and V
low and V
