Pin Function Usage Explanation
Pin 1 (VDD1) and Pin 7 (VDD2): These pins provide power for the logic and isolated sides, respectively. Both should be connected to a stable 5V power source. Pin 2 (VSS1) and Pin 6 (VSS2): These are the ground pins for their respective sides. Make sure they are tied to the common ground of the system. Pins 3 (DIN1) and 10 (DIN2): These are the data input pins. They are used to transmit signals from the non-isolated side (DIN1) to the isolated side (DIN2). Pins 5 (DOUT1) and 8 (DOUT2): These are the data output pins. They carry the signals from the isolated side (DOUT2) to the non-isolated side (DOUT1). Pin 4 (GND1) and Pin 11 (GND2): These serve as the ground reference for the input and output side, respectively. These pins are crucial for proper data transfer across isolation. Pins 12-16 (NC): These are not connected internally in the chip, and should remain unconnected in the circuit.4. Common Questions (FAQ)
