DS2480B+ selection and design context
DS2480B+ is cataloged as a 1-Wire Interface IC in the DS2480B family. Its recorded function is UART-to-1-Wire line driver with selectable communication speed and strong pullup control. Selection should be based on the complete electrical limits, package drawing and ordering suffix rather than the abbreviated family code.
- Host Interface: UART. Confirm logic levels, signaling mode, host support and required external components.
- Network Interface: 1-Wire. Confirm logic levels, signaling mode, host support and required external components.
- Supply Voltage: 4.5 V to 5.5 V. Check rail compatibility, tolerance and sequencing under worst-case conditions.
- UART Rates: 9.6, 19.2, 57.6 and 115.2 kbit/s. Confirm system timing margin and the test conditions attached to the published limit.
Application and qualification considerations
When evaluating this interface device, confirm protocol revision, signaling voltage, data rate, termination, ESD protection, clocking and host-side driver requirements. For a new design, review power-up behavior, interface timing, absolute maximum ratings, thermal limits and any external-component requirements in the latest manufacturer documentation. Existing-board replacement work should additionally confirm pinout, footprint, firmware assumptions and qualification grade.
Procurement checks for DS2480B+
The recorded package is 8-pin SOIC, 150 mil, the temperature range is -40°C to +85°C, and the lifecycle status is Production as of 2026-07-20. Before ordering, confirm the exact MPN on the label, packing format, quantity, date-code requirements, traceability documents and current factory status.
DS2480B+ FAQ
What distinguishes DS2480B+ within the DS2480B family?
