  • ISO7420E: Fail-safe behaviour

    TI Thinks Resolved
    Part Number: ISO7420E We have noticed a behavior in several of our devices that we cannot explain 100%. We have a serial data link with four signals routed via two ISO7420ED. Both isolators are supplied by the same voltage. They are directly next to each…

  • RE: ISO7420FE: Output power down behavior

    Resolved
    Hi Eric, Thank you for posting, and welcome to E2E! The POR for ISO7420 detects when voltage is below its ~3V threshold, and the corresponding outputs become high-impedance (Hi-Z) instead of HIGH or LOW. When local power is not present on the output power…
