DS26521LN

I’m not finding a publicly documented part named DS26521LN from Dallas Semiconductor/Maxim or major distributors. It may be a custom, obsolete, or misread part number. Without an official datasheet I can’t give a reliable intro.
If you can share:
- the manufacturer or a product link, or
- a photo of the package marking,
I’ll summarize precisely.
Otherwise, to locate an intro yourself, check:
- the manufacturer’s datasheet and product page
- distributor catalogs (Digi-Key, Mouser) and cross-reference tools
- package marking guides to confirm the exact part number and function (MCU, interface, transceiver, sensor, etc.)
Once you provide the exact source, I’ll deliver a concise 180-word summary.

I don’t have the DS26521LN datasheet memorized. Please share the datasheet or confirm the device’s function (e.g., clock generator, transceiver, PMIC, etc.). Once I have that, I’ll list the key features concisely (voltage range, interfaces, timing/clock specs, power, temperature, packaging) in 5–7 bullets.

- Manufacturer: Dallas Semiconductor (the DS prefix); the line is now part of Maxim Integrated, which itself is now under Analog Devices.
- What kind of company: an American semiconductor company that designs and manufactures integrated circuits (ICs), including memory, interface, analog/digital ICs.

DS26521LN comes in a 16-pin SSOP (Small-Outline) package.
