Analog Devices DS1374U
DS1374U variants from Analog Devices
DS1374U Overview
What changes between part numbers, and what to check before you lock the BOM — Real Time Clocks.
Key Features
- Footprint / package: 10-TFSOP, 10-MSOP (0.118", 3.00mm Width)Single package option across listed variants; still confirm reel vs tube suffix if you auto-insert.
- Lifecycle mix: ActiveConfirm lifecycle on the exact MPN, not just the base number prefix.
- 3 distinct suffix patternsExamples: 18+, 3+, 33+. Decode suffix meaning in the ordering notes under the variant table.
Target Applications
- Real Time Clocks — design-in and field replacement
- BOM scrub where only the base prefix is known but suffix is TBD
- Second-source checks when the original MPN is constrained
Ordering Variants
Compare 3 DS1374U part numbers by package, electrical parameters, lifecycle, and availability. Use RFQ for stock and lead-time confirmation.
| Part Number | Description | Package Type | Manufacturer | Lifecycle | RoHS | Availability | Action |

How to Choose the Right DS1374U Real Time Clocks
Match the footprint first
Packages here: 10-TFSOP, 10-MSOP (0.118", 3.00mm Width). Open the land-pattern drawing before you substitute a different suffix.
Electrical headroom
Compare voltage and current columns in the variant table. For DS1374U, a suffix with lower voltage or current rating will not survive the same circuit without recalculation.
Temp grade letter matters
Commercial (0–70 °C) and industrial (−40–85 °C+) suffixes look similar in the prefix — confirm ambient + self-heating, not just the first page of the datasheet.
Copy the full MPN
Do not BOM only "DS1374U" — include the full suffix (e.g. 18+, 3+, 33+). RFQ with reel/tube preference and required date code.
