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.
