Overview
The ISO1050DUBR is a galvanically isolated CAN (Controller Area Network) transceiver produced by Texas Instruments. It meets the specifications of the ISO11898-2 standard and is designed to operate in harsh environments. The device features a silicon oxide (SiO2) insulation barrier, providing galvanic isolation of up to 2500 V RMS for the ISO1050DUBR model. This isolation prevents noise currents on the data bus or other circuits from interfering with or damaging sensitive circuitry. The ISO1050DUBR supports differential transmit and receive capabilities at signaling rates up to 1 megabit per second (Mbps) and is compatible with 3.3 V and 5 V microprocessors.
