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.
