FST16292MTDX

Overview

The FST16292MTDX is a high-speed CMOS multiplexer/demultiplexer bus switch manufactured by Fairchild Semiconductor. It integrates twelve independent 1:2 signal switches within a single 56-TSSOP package. The device operates on a single supply voltage ranging from 4V to 5.5V and supports an industrial temperature range of -40°C to 85°C. Designed for surface-mount applications, it provides TTL-compatible logic levels with low on-resistance characteristics suitable for data routing in digital systems.

Feature Summary

• Integrates twelve independent 1:2 multiplexer/demultiplexer channels
• High-speed CMOS technology with TTL-compatible input levels
• Low on-resistance for efficient signal transmission
• Single supply voltage operation

Applications

• Data routing in digital communication systems
• Signal switching in consumer electronics
• Bus expansion interfaces
• Multiplexing control circuits

Procurement Notes

Verify the manufacturer marking matches Fairchild Semiconductor or ON Semiconductor branding. Confirm the 56-TSSOP package type and pin configuration against official datasheets. Ensure the suffix 'MTDX' corresponds to the tape-and-reel packaging format. Check for obsolescence status as component availability may vary across distributors.

Selection Notes

Select this component when twelve independent 1:2 signal paths are required in a compact surface-mount form factor. The 4V to 5.5V supply range suits standard logic families. Consider the 56-TSSOP footprint for PCB layout constraints. Verify thermal performance requirements against the specified operating temperature range.

Part Context

This part belongs to the FST series of high-speed CMOS bus switches. The FST16292 variant specifically consolidates multiple switching functions into one IC, reducing board space compared to discrete solutions. It is designed for applications requiring reliable signal routing with minimal propagation delay.

Replacement Considerations

Check for direct pin-to-pin replacements within the same FST family. Verify electrical parameters such as on-resistance and supply voltage compatibility before substituting.
