AI Summary

SN74LXC1T45QDCKRQ1 by Texas Instruments: Voltage Level Translator Bidirectional 1 Circuit 1 Channel 420Mbps SC-70-6.

This is the commercial-grade sibling of the target part, offering identical electrical and physical characteristics. It is graded as functionally partial because it lacks AEC-Q100 automotive qualification and is only specified for standard industrial temperature conditions.

  • Direct electrical specifications and voltage range (1.1 V to 5.5 V) match the target part exactly.
  • Maintains the exact same SC-70 (DCK) physical package and pin configuration.
  • Lacks AEC-Q100 automotive qualification.
  • Not certified for automotive reliability standards.

This is Texas Instruments' established LVC family equivalent in the same package and automotive grade. It cannot support ultra-low voltage logic level translations below 1.65 V, which makes it functionally partial if 1.2 V or 1.5 V logic interfaces are required.

  • Direct drop-in replacement from the same manufacturer in the identical SC-70 (DCK) footprint.
  • AEC-Q100 Grade 1 qualified for automotive applications (-40°C to 125°C).
  • Excellent option if low-voltage translation below 1.8 V is not required by the application.
  • Restricted supply voltage range of 1.65 V to 5.5 V compared to 1.1 V to 5.5 V on the target.

You searched one part. Parter watches your whole BOM.

  1. All your BOM, at once

    Parter maps every line to live stock, lead time, lifecycle and compliance data across the entire market — not part by part.

  2. Hear about problems before they hit production

    Allocation, EOL and last-time-buy notices surface the moment they appear, not when your buyer's PO bounces.

  3. Qualified replacements in minutes, not days

    Every at-risk line gets form-fit-function matches like the ones above — deltas flagged, evidence attached. Review, push to your BOM, and Parter starts watching the new part too.
