SCANSTA112 7-port Multidrop IEEE 1149.
1 (JTAG) Multiplexer
General Description
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.
Each SCANSTA112 supports up to 7 local IEEE1149.
1 scan chains which can be accessed individually or combined serially.
Addressing is accomplished by loading the instruction register with a value matching that of the Slot inputs.
Backplane and inter-board testing...
