SCANSTA111 Datasheet (Texas Instruments) - Enhanced SCAN Bridge Multidrop Addressable IEEE 1149.1 Port

SCANSTA111, Enhanced SCAN Bridge Multidrop Addressable IEEE 1149.1 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.
