FST34170MTDX

Overview

The FST34170MTDX is a high-speed CMOS TTL-compatible multiplexer/demultiplexer bus switch manufactured by Fairchild Semiconductor. It features a 56-TSSOP package and operates within a voltage supply range of 4V to 5.5V. The device supports an operating temperature range from -40°C to 85°C. It functions as a 16 x 1:2 circuit configuration with one independent circuit, designed for efficient signal routing in digital systems.

Feature Summary

• High-speed CMOS technology compatible with TTL logic levels
• Low on-resistance for efficient signal transmission
• Integrated multiplexer and demultiplexer functionality

Applications

• High-speed data handling systems
• FPGA interface circuits
• Digital signal routing applications

Procurement Notes

Verify the specific suffix 'MTDX' against official datasheets to confirm package type and tape/reel specifications. Confirm RoHS compliance status and lead-free characteristics directly from manufacturer documentation before procurement. Ensure the component matches the required 56-TSSOP form factor for your PCB layout constraints.

Selection Notes

Select this component when a single-supply 4V to 5.5V operation is required for high-speed signal switching. The 56-TSSOP package suits surface-mount designs needing dense pin counts. Verify that the 16-channel capacity meets system requirements without necessitating multiple parallel switches.

Part Context

This part belongs to the FST series of high-speed bus switches. These components are designed to replace slower legacy logic families in modern high-speed digital interfaces. The series typically offers improved power consumption and switching speeds compared to standard CMOS alternatives.

Replacement Considerations

Check for direct substitutes within the same FST family or equivalent ON Semiconductor parts. Verify pin compatibility and electrical parameters before substituting. No confirmed public substitute part numbers are available in the provided source material.
