• Features TTL-compatible control inputs for straightforward integration with standard logic families

Applications

• High-speed data bus switching in industrial control systems
• Signal routing in telecommunications equipment modules
• Peripheral interface management in consumer electronics devices

Procurement Notes

Verify the manufacturer origin, as Fairchild Semiconductor assets were acquired by onsemi. Confirm the specific package type matches the design requirements, noting discrepancies between TSSOP and TFSOP references in various listings. Ensure the component meets current RoHS compliance standards before finalizing procurement orders.

Selection Notes

Select this component when designing systems requiring multiple bidirectional bus switches in a compact form factor. The 56-pin package accommodates extensive channel counts suitable for complex data routing. Evaluate the voltage levels and drive strength requirements against the switch's on-resistance characteristics to ensure compatibility with the target signal sources.

Part Context

This part belongs to the FST series of bus switches, which are widely used for connecting different voltage domains or managing multiple peripheral connections. The series is known for high speed and low power consumption, making it suitable for modern digital interfaces where signal fidelity and timing are critical constraints.

Replacement Considerations

Check for equivalents from onsemi following the acquisition of Fairchild assets. Verify pinout compatibility and electrical specifications against similar 56-pin bus switch solutions if sourcing from alternative manufacturers.
