The Texas Instruments ISO1050DUBR is a galvanically isolated CAN transceiver designed to meet the ISO11898-2 standard. It separates the logic-side interface from the CAN bus through a silicon dioxide (SiO₂) isolation barrier, helping prevent noise currents and ground-potential differences from affecting sensitive circuitry. The DUB version provides 2500 VRMS isolation and supports CAN communication at signaling rates up to 1 Mbps. The device supports 3.3-V and 5-V microprocessors, with a 3-V to 5.5-V logic-side supply and a 4.75-V to 5.25-V bus-side supply. It also features fail-safe outputs, TXD dominant time-out, thermal shutdown, and bus-fault protection from -27 V to 40 V.
The ISO1050DUBR is currently In Stock and ready for immediate shipping at Perceptive Components. With 5K pcs available and Date Code 26+, we support production, maintenance, and urgent sourcing requirements. As a leading independent distributor, we provide verified components, 100% authentic components, competitive sourcing solutions, and reliable global delivery to customers worldwide.
