설계 노트
For optimal isolation performance, maintain proper creepage and clearance distances on the PCB. The wide SOIC-16 package provides 8mm creepage, but ensure the PCB layout also maintains at least 8mm spacing between the isolated grounds. Use a solid ground plane under the device to reduce noise coupling.
Place 0.1µF bypass capacitors close to each VDD pin (VDD1 and VDD2) to decouple high-frequency noise. Additionally, use a 10µF bulk capacitor on each supply rail if the power source is far from the device. This ensures stable operation and reduces supply-induced jitter.
Do not exceed the absolute maximum ratings for supply voltage (7V) or input/output voltages. Ensure that the input signals do not exceed the supply voltage by more than 0.3V. Also, avoid floating unused inputs; tie them to GND or VDD as appropriate to prevent undefined states.
