SCANSTA112SM/NOPB

Specialized Overview

The SCANSTA112SM/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 an operating temperature range from -40°C to +85°C. The device features eight input lines and exhibits a propagation delay of 12 ns. It is housed in a 100-pin nFBGA package suitable for surface-mount technology. This component belongs to the STA112 logic series and is classified under encoders, decoders, multiplexers, and demultiplexers.

Specialized Feature Summary

• Supports 7-port multidrop configuration for JTAG boundary scan networks
• Compatible with IEEE 1149.1 standard protocols
• Operates on low voltage supply ranging from 3 V to 3.6 V

Specialized Applications

• Boundary scan testing systems
• IEEE 1149.1 compliant digital circuit interconnects
• Multidrop multiplexer networks in embedded systems

Specialized Procurement Notes

Verify the specific suffix 'SM/NOPB' against the manufacturer's current datasheet to confirm pinout and packaging details. Ensure compatibility with the target PCB footprint for the 100-nFBGA package. Check for moisture sensitivity level requirements during storage and handling. Confirm that the 3 V to 3.6 V supply range aligns with the system power design. Validate lead times as production cycles may vary.

Specialized Selection Notes

Select this component when a 7-port JTAG multidrop solution is required within the STA112 family. Consider the 100-nFBGA package size for space-constrained designs. Verify that the 12 ns propagation delay meets the timing constraints of the application. Ensure the -40°C to +85°C industrial temperature range is sufficient for the operating environment. Compare with SCANSTA112VS/NOPB if a TQFP package is preferred over BGA.

Specialized Part Context

The SCANSTA112SM/NOPB is part of the SCANSTA112 series from Texas Instruments, specialized for boundary scan multiplexing. It complements other devices like the SCANSTA112EVK/NOPB evaluation kit. The 'NOPB' suffix typically indicates lead-free and RoHS compliance, while 'SM' denotes the specific nFBGA-100 package variant. It serves as a critical interface component in complex digital test architectures.

Specialized Replacement Considerations

SCANSTA112VS/NOPB is a documented alternative offering the same functionality in a 100-TQFP package. Verify pin-to-pin compatibility before substitution. Other variants within the SCANSTA112 family may offer different packaging or thermal characteristics.
