1 V Primary Supply Voltage, 4.5 V to 5.5 V. DD1 2, 8 GND Ground 1. Ground reference for isolator primary. Pin 2 and Pin 8 are internally connected to each other, 1 and it is recommended that both pins be connected to a common ground. 3 V Logic Input A. IA 4 V Logic Input B. IB 5 V Logic Input C. IC 6 V Logic Input D. ID 7 V Logic Power Supply Voltage. This pin must be connected to V and have a dedicated bypass capacitor. DDL DD1 9, 15 GND Ground Reference for Isolator Side 2. Pin 9 and Pin 15 are internally connected to each other, and it is ISO recommended that both pins be connected to a common ground. 10, 16 V Secondary Supply Voltage Output for External Loads, 5.0 V. These pins are not tied together internally ISO and must be connected together on the PCB. 11 V Logic Output D. OD 12 V Logic Output C. OC 13 V Logic Output B. OB 14 V Logic Output A. OA
