FST3384WM

Overview

The FST3384WM is a 10-bit low power bus switch manufactured by Fairchild Semiconductor. It provides high-speed CMOS TTL-compatible bus switching capabilities with a low on-resistance, allowing inputs to be connected to outputs efficiently. The device operates on a single supply voltage ranging from 4V to 5.5V and features separate circuit paths for flexible configuration.

Feature Summary

• Provides 10 bits of high-speed CMOS TTL-compatible bus switching
• Features low on-resistance for efficient signal transmission
• Operates on a single supply voltage

Applications

• High-speed data handling in FPGA systems
• Bus expansion and interconnection in digital circuits
• Signal routing in TTL-compatible logic systems

Procurement Notes

Verify the manufacturer origin, as Fairchild Semiconductor has undergone corporate changes. Confirm the package type matches the required SOP-24 form factor. Ensure the voltage range aligns with your system's 4V to 5.5V requirement. Check for any specific ordering suffixes that might indicate tape-and-reel packaging versus tube quantities if applicable.

Selection Notes

Select this component when a 10-bit bus switch with low on-resistance is needed for TTL-compatible interfaces. It is suitable for applications requiring high-speed data handling within a 4V to 5.5V supply range. Consider the SOP-24 package size for board space constraints. Compare with similar devices like the SN74CBT3384 if alternative sourcing is necessary.

Part Context

The FST3384 series belongs to Fairchild's Switch family, designed for low power and high-speed applications. It complements other bus switches like the FST3383, which offers two sets of switches. This component is part of the broader portfolio of logic ICs used in digital signal processing and interface management.

Replacement Considerations

The SN74CBT3384ADWRE4 from Texas Instruments is a publicly confirmed substitute part number. Verify pin compatibility and electrical specifications before substitution.
