SCANSTA112 Datasheet (Texas Instruments) - 7-Port Multidrop IEEE 1149.1 Multiplexer

SCANSTA112, 7-Port Multidrop IEEE 1149.1 Multiplexer

The SCANSTA112 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.
