10.1 Application Information

The ISO7041 device is an ultra-low power digital isolator. The device uses single-ended CMOS-logic switching technology. The voltage range is from 2.25 V to 5.5 V for both supplies, V_CC1 and V_CC2, and can be set irrespective of one another. When designing with digital isolators, keep in mind that because of the single-ended design structure, digital isolators do not conform to any specific interface standard and are only intended for isolating single-ended CMOS or TTL digital signal lines. The isolator is typically placed between the data controller (that is, μC or UART), and a data converter or a line transceiver, regardless of the interface type or standard. See Isolated power and data interface for low-power applications reference design TI Design for detailed information on designing the ISO70xx in low-power applications.
