SCANSTA112VS/NOPB

Specialized Overview

The SCANSTA112VS/NOPB is a 32-bit multidrop multiplexer designed for IEEE 1149.1 (JTAG) boundary scan applications. Manufactured by Texas Instruments, it operates within a supply voltage range of 3 V to 3.6 V and features a propagation delay of 12 ns. The component supports an extended industrial temperature range from -40°C to +85°C. It is housed in a TQFP-100 surface-mount package with SMD/SMT installation style. This device functions as a specialized logic IC encoder, decoder, and multiplexer, facilitating efficient data routing in multidrop configurations.

Specialized Feature Summary

• Supports 7-port multidrop architecture compliant with IEEE 1149.1 standards
• Provides 32-bit data path capability for high-speed boundary scan operations
• Operates reliably across the full industrial temperature range

Specialized Applications

• IEEE 1149.1 (JTAG) boundary scan test systems
• Multidrop communication networks requiring addressable muxing
• Industrial control systems utilizing enhanced scan bridge protocols

Specialized Procurement Notes

Verify the specific suffix configuration against the official datasheet to ensure compatibility with required operating conditions. Confirm that the TQFP-100 package dimensions match the target PCB footprint. Check humidity sensitivity levels and storage requirements prior to assembly. Ensure the selected variant meets the necessary voltage and temperature specifications for the intended application environment.

Specialized Selection Notes

Select this component when a 32-bit JTAG-compliant multidrop multiplexer is required. Compare the TQFP-100 package constraints against available board space. Evaluate the 12 ns propagation delay against system timing requirements. Consider the SCANSTA112SM/NOPB alternative if a smaller NFBGA-100 package is preferred for the same functional performance.

Specialized Part Context

This part belongs to the SCANSTA112 series of logic ICs focused on encoder, decoder, and multiplexer functions. It is distinct from other TI logic families due to its specific adherence to IEEE 1149.1 multidrop standards. The VS/NOPB designation indicates the TQFP-100 package variant without lead-based solder, differentiating it from the SM/NOPB BGA version.

Specialized Replacement Considerations

The SCANSTA112SM/NOPB serves as a direct functional substitute offering identical electrical characteristics but utilizes an NFBGA-100 package instead of TQFP-100. Verify pinout compatibility and thermal management requirements when switching between these package types.
