    ISO1042DWV

    The ISO1042 device is a galvanically-isolated
    controller area network (CAN) transceiver that meets
    the specifications of the ISO11898-2 (2016) standard.
    The ISO1042 device offers ±70-V DC bus fault
    protection and ±30-V common-mode voltage range.
    The device supports up to 5-Mbps data rate in CAN
    FD mode allowing much faster transfer of payload
    compared to classic CAN. This device uses a silicon
    dioxide (SiO2
    ) insulation barrier with a withstand
    voltage of 5000 VRMS and a working voltage of 1060
    VRMS. Electromagnetic compatibility has been
    significantly enhanced to enable system-level ESD,
    EFT, surge, and emissions compliance. Used in
    conjunction with isolated power supplies, the device
    protects against high voltage, and prevents noise
    currents from the bus from entering the local ground.
    The ISO1042 device is available for both basic and
    reinforced isolation (see Reinforced and Basic
    Isolation Options). The ISO1042 device supports a
    wide ambient temperature range of –40°C to +125°C.
    The device is available in the SOIC-16 (DW) package
    and a smaller SOIC-8 (DWV) package.
