Part Review and Datasheet Verification

A

adrian95

Review all available part information (MPN, package, pin count, description, properties). If no datasheet URL is already set, search the web for the official datasheet and update the part's Datasheet property with the URL. Then cross-check the schematic symbol, footprint, and pin descriptions against the datasheet. Summarize key specs and flag any mismatches.

I’ll review the part metadata, find and attach the official datasheet if needed, then compare symbol, footprint, and pin descriptions against the datasheet.

Completed the part review and documented the detailed findings in 74HC238N Part Review Results (74hc238n-part-review-results). The schematic pinout matches the datasheet, and the footprint appears consistent with DIP16/SOT38-4 at the outline level.
Open items / flags:
  • Package or Case Code is set to TO; it should be DIP16 / SOT38-4.
  • All terminal Pin Type properties are Unspecified; they should ideally be Input, Output, Power, or Ground.
  • Datasheet URL was already set, so I did not overwrite it, but the official Nexperia URL is https://assets.nexperia.com/documents/data-sheet/74HC_HCT238.pdf.
  • Exact pad/drill geometry could not be fully verified from the available layout inspection output.
Suggested next steps:
  1. Update the package property to DIP16 or SOT38-4.
  2. Set datasheet-based pin types for all terminals.
  3. Optionally replace the uploaded datasheet URL with the official Nexperia URL.
