FST3384QSC

Overview

The FST3384QSC is a 10-bit high-speed CMOS TTL-compatible bus switch manufactured by Fairchild Semiconductor. It features dual independent circuits, each providing five bits of switching capability within a single package. The device operates with a supply voltage range of 4V to 5.5V and utilizes a 24-pin SSOP package. Key electrical characteristics include a low on-resistance for efficient signal transmission and a fast propagation delay of 250ps. The component is designed for applications requiring low quiescent current and robust signal integrity in digital systems.

Feature Summary

• Provides ten bits of high-speed CMOS bus switching functionality
• Features dual independent circuits for flexible system configuration
• Ensures low on-resistance for effective input-to-output connection
• Supports TTL-compatible logic levels for broad interface compatibility

Applications

• High-speed data bus interconnects
• Digital signal routing in communication equipment
• System board level signal switching
• Portable electronic devices requiring low power consumption

Procurement Notes

Verify the obsolete status of this part number before procurement planning. Confirm that the 24-pin SSOP package matches your PCB footprint requirements. Ensure the 4V-5.5V operating voltage aligns with your system design. Check for RoHS compliance documentation if required by your manufacturing standards. Consider alternative components due to potential availability constraints.

Selection Notes

Select this component when ten bits of bus switching are required in a compact form factor. The dual independent circuit architecture allows for separate control of two five-bit groups. The low on-resistance makes it suitable for maintaining signal integrity across longer traces. The wide supply voltage range accommodates various system power rails. Verify that the propagation delay meets your timing specifications.
