Pin Function Descriptions:
1. VDD1 (Pin 1): Function: This is the power supply pin for the input side of the isolator. A positive supply voltage is applied to this pin to power the input circuitry. 2. VSS1 (Pin 2): Function: This is the ground reference for the input side of the isolator. It should be connected to the ground of the system where the isolator is being used. 3. I/O1+ (Pin 3): Function: This is the positive signal input/output pin for channel 1. It carries the data signal that is being transmitted or received. 4. I/O1- (Pin 4): Function: This is the negative signal input/output pin for channel 1. It works together with I/O1+ to transmit or receive differential signals. 5. I/O2+ (Pin 5): Function: This is the positive signal input/output pin for channel 2. Like I/O1+, it carries the data signal. 6. I/O2- (Pin 6): Function: This is the negative signal input/output pin for channel 2. It works in conjunction with I/O2+ to transfer differential data. 7. VSS2 (Pin 7): Function: This is the ground reference for the output side of the isolator. It should be connected to the ground of the isolated system. 8. VDD2 (Pin 8): Function: This is the power supply pin for the output side of the isolator. A positive voltage is applied to this pin to power the output side circuitry. 9 to 16. NC (No Connect) (Pins 9 to 16): Function: These pins are not connected internally to the circuit and are reserved for potential future use or for different package configurations.3. Common FAQs:
