Procurement Notes

Verify the specific manufacturer source, as Fairchild Semiconductor has undergone integration processes that may affect part numbering or documentation availability. Confirm the package type matches the required 56-SSOP form factor. Ensure the component meets the specified voltage and temperature operational ranges for your target application environment before finalizing procurement decisions.

Selection Notes

Select this component when a 24-bit wide bus switch is required with TTL compatibility. The 56-SSOP package suits applications needing moderate pin counts in compact layouts. Consider the 4V to 5.5V supply requirement and ensure the system design accommodates the specified operating temperature range of -40°C to 85°C for reliable performance.

Part Context

This component belongs to the FST series of bus switches designed for high-speed digital applications. It serves as a critical interconnect element in systems requiring flexible signal routing. The device integrates multiple switch channels into a single package, reducing board space compared to discrete solutions while maintaining signal fidelity across the bus width.

Replacement Considerations

Check for direct equivalents within the same product family or cross-reference with other manufacturers offering similar 24-bit bus switches in SSOP packages. Verify pinout compatibility and electrical specifications such as on-resistance and supply voltage ranges to ensure functional interchangeability without circuit redesign.
