SCANSTA112SM

Specialized Overview

The SCANSTA112SM is a logic IC from Texas Instruments, classified under encoders, decoders, multiplexers, and demultiplexers. It functions as a 7-port multidrop IEEE 1149.1 (JTAG) multiplexer. The device is housed in an nFBGA-100 package. It operates within a temperature range of -40°C to +85°C. The component is part of the SCANSTA112 series and is designated with the manufacturer number SCANSTA112SM.

Specialized Feature Summary

• Supports 7-port multidrop IEEE 1149.1 (JTAG) standard
• Functions as a multiplexer for scan chain management

Specialized Applications

• JTAG scan chain multiplexing
• Board-level test access routing

Specialized Procurement Notes

Verify the specific suffix 'SM' against the official datasheet to confirm package type and commercial availability. Confirm RoHS status and moisture sensitivity level requirements for your assembly process. Check for the existence of the SCANSTA112EVK/NOPB development kit for evaluation purposes.

Specialized Selection Notes

Select this component when a 7-port JTAG multiplexer in an nFBGA-100 package is required. Ensure the design supports the -40°C to +85°C operating temperature range. Compare with the SCANSTA112VS/NOPB variant if a TQFP-100 package is preferred instead of the BGA form factor.

Specialized Part Context

This part belongs to the SCANSTA112 family of JTAG multiplexers manufactured by Texas Instruments. It is designed to manage multiple scan chains in complex digital systems. The SM suffix typically denotes a specific tape-and-reel or tray packaging configuration distinct from other variants like VS.

Specialized Replacement Considerations

The SCANSTA112VS/NOPB is a documented alternative offering the same functionality in a 100-TQFP package. Verify pin compatibility and thermal performance differences before substitution.
