JAJSGE1A October 2018 – October 2019 ISO1042-Q1
The ISO1042-Q1 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-Q1 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.
