SCANSTA112SMX/NOPB

The Texas Instruments SCANSTA112SMX/NOPB is a specialized interface IC that functions as a 7-port multidrop IEEE 1149.1 (JTAG) multiplexer. This device is designed for applications in testing equipment, offering a robust solution for managing JTAG scan chains.

Key electrical characteristics include a supply voltage range of 3.0V to 3.6V. The operating temperature range is specified from -40°C to 85°C, ensuring reliable performance in various environmental conditions. The multiplexer supports hierarchical and multidrop addressable capability, with 8 address inputs accommodating up to 249 unique slot addresses, an interrogation address, a broadcast address, and 4 multi-cast group addresses.

It features 7 IEEE 1149.1-compatible configurable local scan ports. The bi-directional backplane and LSP 0 ports are interchangeable slave ports. Advanced modes like Stitcher Mode and Transparent Mode are supported, allowing for flexible scan chain configuration and buffering. General purpose local port pass-through bits are useful for tasks such as flash programming or monitoring device status.

The SCANSTA112SMX/NOPB comes in a 100-FBGA (10x10) package, designed for surface mounting. This packaging ensures efficient integration into compact electronic designs. The device also supports live insertion/withdrawal, adding to its versatility in complex test setups.
