This information is based on the manufacturer's datasheet and technical documentation.

Application Scenarios & Design Considerations

Enhanced SCAN bridge Multidrop Addressable IEEE 1149.1 (JTAG) Port

Alternative Part Number

  • DS90CR286MTDX --: TI acquired National Semiconductor, so this is a same-family channel-link device in the same TSSOP-style package and is a common drop-in substitute for SCANSTA111 boundary-scan bridge applications.
  • SN65LVDS386DGG --: LVDS receiver/bridge in a similar package with comparable signaling and supply requirements, suitable as a functional replacement when exact SCANSTA111 features are not required.
  • MAX9217ECM+ --: Serializer/deserializer bridge IC with similar interface role and package options, usable as an alternative when the SCANSTA111 is unavailable.
