Description
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; connecting both
pins to GND
Logic Input A.
Logic Input B.
Logic Input C.
No Connect.
Input Disable. Disables the isolator inputs and refreshes. Outputs take on logic state determined
by CTRL.
Ground 1. Ground reference for Isolator Side 1. Pin 8 and Pin 2 are internally connected; connecting both
pins to GND
Ground 2. Ground reference for Isolator Side 2. Pin 9 and Pin 15 are internally connected; connecting both
pins to GND
Default Output Control. Controls the logic state the outputs take on when the input power is off. V
