Texas Instruments' ISO1042 is an isolated CAN transceiver with ±70 V DC bus fault protection and flexible data rate

Texas Instruments' 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 VDCbus 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. Used in conjunction with isolated power supplies, the device prevents noise currents on a data bus or other circuits from entering the local ground and interfering with or damaging sensitive circuitry. The ISO1042 device is available for both basic and reinforced isolation.

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.
