Overview
The ISO1050DUB is a galvanically isolated CAN (Controller Area Network) transceiver produced by Texas Instruments. It is designed to meet the specifications of the ISO11898-2 standard, ensuring reliable communication in harsh environments. The device features a silicon oxide (SiO2) insulation barrier that provides galvanic isolation, protecting sensitive circuitry from noise currents and other forms of interference. It is particularly useful in applications requiring high isolation and robustness against various types of faults and environmental stresses.
