• Integrates twelve independent 1:1 signal switching circuits for flexible data path management
• Operates on a single voltage supply rail between 4V and 5.5V
• Engineered for high-speed signal transmission with low propagation delay characteristics

Applications

• High-density data routing in consumer electronics
• Signal isolation in industrial control systems
• Bus expansion interfaces in computing hardware

Procurement Notes

Verify the obsolete status of this component before procurement planning. Confirm availability through authorized distributors or secondary market suppliers. Ensure RoHS compliance documentation is available if required for specific regulatory environments. Check for lead-free packaging specifications to meet environmental standards.

Selection Notes

Select this component when twelve independent bidirectional switches are required in a compact form factor. Consider the 4V to 5.5V operating range for compatibility with 5V logic systems. Evaluate the FBGA package constraints for PCB layout requirements. Verify that the signal speed requirements align with the device's propagation delay specifications.

Part Context

This part belongs to the FST series of bus switches, designed for high-performance signal switching applications. The GX suffix typically indicates a specific package variant, often associated with fine-pitch ball grid array configurations. Fairchild Semiconductor, now part of ON Semiconductor, produced this line for robust digital signal routing needs.

Replacement Considerations

The FST32211G is a comparable pin-compatible alternative from the same manufacturer family. Verify package dimensions and electrical parameters against the original specification. Ensure functional equivalence regarding channel count and voltage operation before substitution.
