8.1 Overview

The ISO1042 device is a digitally isolated CAN transceiver that 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. The ISO1042 device has an isolation withstand voltage of 5000 VRMS and is available in basic and reinforced isolation with a surge test voltage of 6 kVPK and 10 kVPK respectively. The device can operate from 1.8-V, 2.5-V, 3.3-V, and 5-V supplies on side 1 and a 5-V supply on side 2. This supply range is of particular advantage for applications operating in harsh industrial environments because the low voltage on side 1 enables the connection to low-voltage microcontrollers for power conservation, whereas the 5 V on side 2 maintains a high signal-to-noise ratio of the bus signals.
