Overview
The ISO1042DWV is a galvanically-isolated Controller Area Network (CAN) transceiver produced by Texas Instruments. It meets the specifications of the ISO 11898-2:2016 standard and is designed to provide robust and reliable communication in harsh industrial environments. The device offers ±70-V DC bus fault protection and a ±30-V common-mode voltage range, ensuring high reliability and protection against electrical faults. It supports both classic CAN up to 1 Mbps and CAN FD (Flexible Data Rate) up to 5 Mbps, enabling faster data transfer. The ISO1042DWV is available in an 8-pin SOIC (DWV) package and operates over a wide ambient temperature range of –40°C to +125°C.
