Completed the review and saved the full findings in Part Verification Report: SN74HC123N. The main issue is a part-identity mismatch: the project is labeled SN74HC123N, but the populated datasheet and key specs match TI’s SNx4AHCT123A family; the pin order and PDIP-16 footprint look broadly compatible, but pin types/descriptions are incomplete.
Open items:
  • Datasheet URL was already set, so I did not change it.
  • I filed an internal part-quality report for the metadata/datasheet mismatch.
Suggested next steps:
  1. Decide whether this part should be SN74AHCT123AN, SN74AHC123AN, CD74HC123E, or a verified SN74HC123N.
  2. Update the MPN/datasheet/description to the selected family.
  3. Add terminal Pin Type and Pin Description properties from the correct datasheet.

Use SN74AHC123AN and update the part metadata against the official AHC datasheet.

I’ll switch the part identity to SN74AHC123AN, use TI’s official AHC datasheet, update the key metadata and terminal properties, then verify the changes.

flux

Part name, description, datasheet URL, MPN, manufacturer, package, and key operating metadata are updated to SN74AHC123AN; now I’m filling in the terminal pin types/descriptions.

flux

Updated the part to SN74AHC123AN and verified it against TI’s official SNx4AHC123A datasheet. Metadata now reflects the AHC part, 2 V–5.5 V operating range, PDIP-16 N package, TI manufacturer, and the terminal pin types/descriptions are populated from the datasheet.
Open items:
  • None.
Suggested next steps:
  1. Review/publish the updated part.
  2. Optionally re-run a full part QA review before using it in another design.
