The ISO1042-Q1 device is a galvanically-isolated controllerarea network (CAN) transceiver that meets the specifications of the ISO11898-2 (2016) standard. TheISO1042-Q1 device offers ±70-V DC bus fault protection and ±30-Vcommon-mode voltage range. The device supports up to 5-Mbps data rate in CAN FD mode allowing muchfaster transfer of payload compared to classic CAN. This device uses a silicon dioxide(SiO2) insulation barrier with a withstand voltage of 5000VRMS 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 deviceprotects against high voltage, and prevents noise currents from the bus from entering the localground. The ISO1042-Q1 device is available for both basic andreinforced isolation (see Reinforced and Basic Isolation Options). TheISO1042-Q1 device supports a wide ambient temperature range of –40°Cto +125°C. The device is available in the SOIC-16 (DW) package and a smaller SOIC-8 (DWV)package.
