Selection Notes

  • Good for: high-speed digital signal muxing, selectable buses, low-resistance routing, and compact interface switching
  • Known layout constraints: Verify package land pattern, decoupling requirements, thermal pad, RF keepouts, crystal routing, and boot straps from the datasheet.
  • Equivalent search hints: match category bus-switch, interfaces gpio, package SSOP-16-4.4mm, and EasyEDA footprint UUID 5ad461650689455ab838a85bfd5f6099.
