SCANSTA112VSX/NOPB

Specialized Overview

The SCANSTA112VSX/NOPB is a 7-port multidrop IEEE 1149.1 (JTAG) multiplexer manufactured by Texas Instruments. It operates within an industrial temperature range of -40°C to +85°C and utilizes a 100-pin TQFP package. The device supports 3.6 V logic levels and is designed for high-speed signal routing in test and measurement applications. It integrates encoder, decoder, multiplexer, and demultiplexer functionalities into a single integrated circuit, facilitating efficient management of multiple JTAG chains.

Specialized Feature Summary

• Supports 7-port multidrop configuration for IEEE 1149.1 (JTAG) standards
• Integrates encoding, decoding, multiplexing, and demultiplexing capabilities
• Operates reliably across the full industrial temperature range

Specialized Applications

• Multidrop JTAG chain management in embedded systems
• Test and measurement equipment requiring multiple target connections
• Board-level debugging interfaces with multiple devices

Specialized Procurement Notes

Verify the specific suffix 'VSX' against official Texas Instruments documentation to confirm package type and tape-and-reel specifications. Ensure compatibility with existing PCB footprints for the 100-pin TQFP form factor. Check for moisture sensitivity level requirements during storage and handling procedures prior to assembly.

Specialized Selection Notes

Select this component when a single IC must manage seven distinct JTAG ports without external switching complexity. Confirm that the 100-pin TQFP package fits the available board space and thermal constraints. Verify that the operating voltage and temperature range align with the system's environmental and power specifications.
