The ISO1042DWR from Texas Instruments is a high-performance isolated CAN (Controller Area Network) transceiver that ensures robust communication in noisy industrial environments. This transceiver is designed to provide galvanic isolation between the CAN bus and the microcontroller, enhancing safety and reliability for systems requiring CAN communication.

Key Features

• Isolation: The device offers up to 5000 VRMS (1 minute) isolation and a working voltage of 1060 VPEAK, providing a high degree of protection against voltage spikes and surges commonly found in industrial settings.
• Signal Rates: It supports the CAN FD standard and is capable of data rates up to 5 Mbps, making it suitable for high-speed data transmission required in modern industrial applications.
• Robustness: The ISO1042DWR is characterized by its robust electromagnetic compatibility (EMC), including high immunity to electromagnetic interference (EMI) and low emissions that minimize the impact on other electronic devices.
• Temperature Range: It operates over an industrial temperature range of -55°C to +125°C, ensuring reliable performance in extreme conditions.
• Package: The device comes in a 16-pin SOIC (DWR) package, which is suitable for space-constrained applications while providing enough pins for all necessary connections.
