    [FAQ] ISOM8110: How do I design ISOM8110 to have the best timing performance for switching applications?

    Part Number: ISOM8110

    Tool/software:

    FAQ: Isolation >> Opto-Emulators >> Current FAQ

    The ISOM8110 is designed for analog behavior. Switching performance is possible and depends on the circuit design. However, we need to pay attention to the test conditions to make sure the output transistor is in saturation mode (being used as a switch).
