Texas Instruments
1/1 Transceiver Full CANbus 16-SOIC
NRND740 in stock

Overview

The ISO1042DW is a galvanically isolated CAN transceiver supporting data rates up to 5 Mbps in CAN FD mode. It provides 70V DC bus-fault protection and a wide common-mode voltage range of +/-30V, making it highly resilient to ground offsets and electrical noise in harsh environments.

Why Choose This Part

This transceiver offers a high level of protection with +/-70V bus fault tolerance and +/-16 kV HBM ESD protection. Its wide supply range on the controller side (1.71V to 5.5V) allows direct interfacing with modern low-voltage FPGAs and microcontrollers without level shifters.

Applications

Industrial Automation
Used in factory PLC systems and motor control units where high CMTI of 100 kV/microsecond is required to maintain signal integrity.
Electric Vehicle Charging
Provides the necessary isolation between high-voltage power electronics and low-voltage control logic in EV charging stations.
Solar Inverters
Enables reliable CAN communication in power conversion systems that experience significant electrical transients and potential differences.
