Texas Instruments SN54ALS
SN54ALS variants from Texas Instruments
SN54ALS Overview
What changes between part numbers, and what to check before you lock the BOM — Microcontrollers.
Key Features
- Footprint / package: 16-CDIP (0.300", 7.62mm)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.
- 10 distinct suffix patternsExamples: 00AJ, 109AJ, 10AJ, 273J, 27AJ (+5 more). Decode suffix meaning in the ordering notes under the variant table.
Target Applications
- Microcontrollers — 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 Code Differences
How suffixes on SN54ALS map to package, grade, and reel options.
How to Choose the Right SN54ALS Microcontrollers
Match the footprint first
Packages here: 16-CDIP (0.300", 7.62mm). Open the land-pattern drawing before you substitute a different suffix.
Electrical headroom
Compare voltage and current columns in the variant table. For SN54ALS, 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 "SN54ALS" — include the full suffix (e.g. 00AJ, 109AJ, 10AJ). RFQ with reel/tube preference and required date code.
