Rated for 5000 Vrms isolation and 50 Mbps data rate, it handles CAN FD frames comfortably while keeping the bus domain electrically isolated from the controller side. The 2/2 input-side/side-2 split gives two downstream and two upstream channels — the natural fit for a CAN transceiver with TX/RX plus a wake and fault line.
Yes, the ISO6742FQDWRQ1 is AEC-Q100 qualified, making it suitable for automotive applications requiring the AEC-Q100 reliability standard.
The ISO6742FQDWRQ1 supports a data rate of 50 Mbps, sufficient for CAN FD and other high-speed serial protocols.
The closest functional alternative is the ISO6742FDWR, which shares the same 50 Mbps data rate, 5000 Vrms isolation, and 2/2 channel configuration but lacks AEC-Q100 automotive qualification. For designs that need the automotive grade, the Q1 suffix part is the correct choice.
The device type is CAN (general-purpose digital isolator for CAN bus and other interfaces), and the grade is Automotive, confirmed by AEC-Q100 qualification.
