Pin Function Descriptions
VDD1 & VSS1 (Pins 1 and 2): These pins supply the power for the primary side (input side). VDD1 is connected to a +5V power source, and VSS1 is connected to the ground. It is critical to maintain a stable voltage to ensure proper isolation and data transmission.
SDI1 & SDO1 (Pins 3 and 4): These are the data input and output pins for the primary side of the isolator. SDI1 (Serial Data Input) allows data to enter the device, while SDO1 (Serial Data Output) sends data out to other components in the circuit.
SCK1 (Pin 5): The Serial Clock Input (SCK1) synchronizes the data transmission between the primary side and secondary side of the isolator. It operates with the SDI1 and SDO1 to ensure that data is transferred at the correct timing.
RST1 (Pin 6): The Reset pin for the primary side. When activated, it resets the internal logic of the isolator to a known state, allowing for fresh initialization of the system.
CS1 (Pin 7): The Chip Select pin for the primary side. It enables communication with the isolator when the chip select is active.
VDD2 & VSS2 (Pins 8 and 9): These pins provide the power for the secondary side (output side) of the isolator. VDD2 is connected to a +5V power supply, and VSS2 is connected to the ground. Similar to VDD1 and VSS1, stable voltage is essential for reliable isolation.
SDI2 & SDO2 (Pins 10 and 11): These are the data input and output pins for the secondary side. SDI2 receives data from the primary side, while SDO2 sends data back to the primary side, allowing for bidirectional communication.
SCK2 (Pin 12): The Serial Clock Output pin for the secondary side. It ensures the data from SDI2 is synchronized with the primary side by using this clock signal.
RST2 (Pin 13): The Reset pin for the secondary side. This pin ensures that the secondary side logic can be reset independently of the primary side logic when required.
CS2 (Pin 14): The Chip Select pin for the secondary side. It controls the activation of the secondary side communication, similar to CS1 on the primary side.
NC (Pins 15 and 16): These are Not Connected pins, meaning they are not used in the device and do not have any electrical functionality.
