FSTU32160AMTD

Overview

The FSTU32160AMTD is a 16-bit to 32-bit multiplexer/demultiplexer bus switch manufactured by Fairchild Semiconductor. It belongs to the FSTU series, which integrates -2V undershoot protection for enhanced signal integrity. The device operates as a high-speed data routing component suitable for parallel bus applications.

Feature Summary

• Integrates -2V undershoot protection circuitry to safeguard connected logic inputs from voltage transients.
• Functions as a bidirectional multiplexer or demultiplexer for 16-bit and 32-bit data buses.
• Designed for high-speed switching applications requiring reliable signal transmission.

Applications

• High-speed parallel data bus routing
• Multiplexing and demultiplexing in digital systems
• Signal integrity enhancement in communication interfaces

Procurement Notes

Verify the manufacturer source, as Fairchild Semiconductor's semiconductor division was acquired by onsemi. Ensure the specific part number matches current availability from authorized distributors or legacy stock holders. Confirm package type and pinout compatibility with the target PCB design before procurement.

Selection Notes

Select this component when designing systems that require robust protection against negative voltage undershoots on data lines. It is appropriate for applications needing efficient management of wide data buses without external protection components. Evaluate the operating voltage range and speed requirements against system specifications.

Part Context

This component is part of the FSTU family of bus switches. These devices are engineered to provide low on-resistance and effective signal isolation. The inclusion of undershoot protection distinguishes it from standard bus switches, making it suitable for sensitive digital environments.

Replacement Considerations

The FSTU32160A is a related variant within the same product line. Verify functional equivalence regarding the presence of undershoot protection features when considering substitutes. Cross-reference pinouts and electrical characteristics with alternative manufacturers' offerings if sourcing becomes constrained.
