Analog Devices / Maxim / Dallas — multiple entities (MA-L); chipset maker, OUI ≠ device brand
Summary
- // what this is
- Analog Devices is registered to MAC prefix
00:05:F7and 5 more in the IEEE OUI database. When a device's MAC address begins with00:05:F7, that block was registered by Analog Devices — the OUI identifies the maker of the network hardware, which is not always the brand on the device. - // analyst note
- A Dallas (00:60:35) or ADI ID typically appears on industrial/embedded gear or as a 1-Wire/iButton serialized identifier, not on a consumer-branded box.
About this vendor.
Analog Devices' MAC footprint spans IEEE registrants that should be aliased to one family: "Analog Devices, Inc." (~5 blocks), the separate legacy "MAXIM INTEGRATED PRODUCTS" (count unresolved this pass), and "DALLAS SEMICONDUCTOR, INC." (1 block). Verified ADI samples include 00:05:F7, 00:60:88, 00:E0:22, 78:C6:BB, and 90:94:0A; the Dallas sample is 00:60:35 (registered at 4401 South Beltwood Parkway, Dallas, TX). ADI's own address is in Wilmington/Norwood, MA. These OUIs appear on mixed-signal/analog ICs, microcontrollers, the Dallas/Maxim 1-Wire and iButton parts (which generate EUI-48/EUI-64 identifiers directly from the chip), and industrial/IoT connectivity. The corporate history explains the multiple names: ADI completed its acquisition of Maxim Integrated Products on 2021-08-26 (~$21 billion all-stock, 0.63 ADI share per Maxim share), and Maxim had earlier acquired Dallas Semiconductor (2001); both "Maxim Integrated Products" and "Dallas Semiconductor, Inc." remain distinct legacy registrants. The key analyst point is the chipset pattern: an ADI/Maxim/Dallas OUI identifies the silicon vendor, not the device brand. For triage, a Dallas (00:60:35) or ADI ID typically appears on industrial/embedded gear or as a 1-Wire/iButton serialized identifier, not on a consumer-branded box.

- Special note
- An ADI/Maxim/Dallas OUI identifies the silicon vendor, not the device brand. The 1-Wire/iButton scheme deliberately derives EUI-48/EUI-64 identifiers directly from the chip. "Maxim Integrated Products" and "Dallas Semiconductor, Inc." remain distinct legacy registrants. NOTE: the common guess 00:0A:DC is actually RuggedCom Inc., NOT Maxim. The IEEE registry publishes no assignment dates, so none is stated here. [Confirmed]
