The ISO1042 device is a galvanically-isolated controller area network (CAN) transceiver that meets the specifications of the ISO11898-2 (2016)
standard. 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 like R1SX from RECOM, the device prevents noise currents on a data bus or other circuits from entering the local ground and
interfering with or damaging sensitive circuitry.
ISO1042 accepts 1.8V, 2.5V, 3.3V or 5.5V supply voltage on the primary side (VCC1) and 5V on the secondary (VCC2).
