SCANSTA112VS

Specialized Overview

The SCANSTA112VS/NOPB is a 7-port 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 supports 32-bit data paths. The device features a propagation delay of 12 ns and functions reliably across an industrial temperature range from -40°C to +85°C. Packaged in a TQFP-100 surface-mount format, it integrates multiplexing capabilities for test access ports. The component is moisture-sensitive and requires appropriate handling during assembly.

Specialized Feature Summary

• Supports 7-port multidrop configuration for JTAG boundary scan networks
• Compatible with IEEE 1149.1 standard protocols
• Operates on low-voltage power supplies between 3 V and 3.6 V

Specialized Applications

• Boundary scan testing infrastructure
• IEEE 1149.1 compliant system interconnects
• Multidrop test access port routing

Specialized Procurement Notes

Verify the specific suffix against official datasheets, as variations such as /NOPB indicate lead-free compliance. Confirm package type and operating temperature range match design requirements. Check humidity sensitivity classification for proper storage and reflow soldering profiles. Ensure compatibility with existing JTAG controller logic levels.

Specialized Selection Notes

Select this component when a 7-port JTAG multidrop solution is required within the specified voltage and temperature constraints. Compare pinout and electrical characteristics with similar devices like the SCANSTA112SM variant if board space differs. Validate that the TQFP-100 package fits the PCB layout constraints and thermal management strategy.

Specialized Part Context

This part belongs to the SCANSTA112 family of logic ICs focused on encoder, decoder, and multiplexer functions. It serves as a specialized interface for test and measurement systems requiring robust multidrop connectivity. The series includes variants with different packages to accommodate various manufacturing needs.

Specialized Replacement Considerations

The SCANSTA112VSX/NOPB is a related variant within the same product line. Verify functional equivalence and pin compatibility before substitution. Other family members may offer different packaging options but share core operational principles.
