FSTU6800MTCX

Overview

The FSTU6800MTCX is a 10-bit bus switch manufactured by Fairchild Semiconductor, housed in a 24-TSSOP package. It provides high-speed CMOS TTL-compatible bus switching with precharged outputs and VCC undershoot protection. The device operates within a supply voltage range of 4V to 5.5V. Key electrical characteristics include low on-resistance for efficient signal routing and compatibility with standard digital logic levels.

Feature Summary

• Provides 10 bits of high-speed CMOS bus switching capability
• Features precharged outputs to minimize signal reflections
• Includes VCC undershoot protection for system reliability
• Maintains TTL compatibility for broad interface integration

Applications

• High-speed data routing in digital systems
• Signal multiplexing and demultiplexing interfaces
• Bus expansion and bridging applications

Procurement Notes

Verify the manufacturer marking and date code against official Fairchild or ON Semiconductor documentation. Confirm the 24-TSSOP package integrity and pin alignment. Ensure the component matches the specific suffix requirements for your assembly process. Cross-reference the part number with authorized distributor lists to avoid counterfeit sources.

Selection Notes

Select this component when a 10-channel bidirectional switch is required for 5V logic systems. The TSSOP-24 package suits space-constrained PCB layouts. Consider the low on-resistance for minimal signal degradation. Verify that the operating voltage range aligns with the target system's power supply specifications.

Part Context

This device belongs to the Fairchild Switch family, designed for high-performance signal routing. It complements other logic switches by offering enhanced protection features like undershoot immunity. The product line targets applications requiring reliable data transfer across multiple buses without significant latency.

Replacement Considerations

Check for direct equivalents such as the FSTU6800WM variant if package differences are acceptable. Verify pin-to-pin compatibility before substituting. Ensure the replacement maintains the same 10-bit configuration and voltage ratings.
