3 Description
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.
