SCANSTA111 Datasheet - National Semiconductor

SCANSTA111 Enhanced SCAN bridge Multidrop Addressable IEEE 1149.1 (JTAG) Port

The SCANSTA111 extends the IEEE Std. 1149.1 test bus into a multidrop test bus environment. The advantage of a multidrop approach over a single serial scan chain is improved test throughput and the ability to remove a board from the system and retain test access to the remaining modules. Each SCANST.
