Product Overview
ISO1050DUBR is a Texas Instruments isolated CAN transceiver for Signal_Chain applications requiring a CAN interface with galvanic isolation. The device meets ISO11898-2 requirements and supports CAN transmit and receive operation up to 1 Mbps. Its isolation barrier is silicon oxide (SiO2), positioned between the logic input/output buffers and the bus-side circuitry.
For the ISO1050DUB variant, the stated isolation voltage is 2500 VRMS. The related ISO1050DW variant is specified at 5000 VRMS and uses the SOIC (16), 10.3 mm × 10.3 mm package option, while ISO1050DUBR uses the SOP (8), 9.5 mm × 10.4 mm package option. Device timing includes 150 ns typical loop delay and 210 ns maximum loop delay.
Protection and operating features include -27 V to 40 V CAN bus fault protection, -12 V to 12 V CAN common-mode range, dominant timeout, fail-safe outputs, overtemperature shutdown, cross-wire protection, overvoltage protection, and loss of ground protection. The logic interface supports both 3.3 V and 5 V microprocessor connections.

Procurement Notes
When requesting a quote for ISO1050DUBR, buyers should confirm the manufacturer, package or case, required quantity, target date code, compliance documents, packing method, destination country and expected delivery schedule.
If alternatives are acceptable, buyers should share the approved vendor list, required electrical or optical limits, package constraints and qualification requirements. Any alternative part should be reviewed by the buyer's engineering team before production use.
For analog and signal-chain sourcing, supply voltage, bandwidth, accuracy, noise level, package, temperature grade, input/output configuration and qualification requirements should be verified before approval.
