Specialized Procurement Notes

Verify component authenticity through authorized distributors or original manufacturer channels. Confirm RoHS compliance status and specific ordering suffixes against current datasheets. Check for obsolescence notices or lifecycle changes, as Fairchild products may have transitioned to ON Semiconductor branding.

Specialized Selection Notes

Select this component when designing circuits requiring USB 2.0 signal routing with minimal power consumption. Ensure the design accommodates the 3.3 V operating voltage. Verify that the SC-70-6 package footprint matches the PCB layout requirements. Consider thermal dissipation capabilities within the small package for the intended application load.

Specialized Part Context

This part belongs to Fairchild's family of USB 2.0 switches, which also includes variants like the FSUSB23. These components are engineered to provide efficient signal path management in space-constrained electronic devices. The series emphasizes low insertion loss and high isolation between switched ports.

Specialized Replacement Considerations

Compatible substitutes include the FSUSB23 and FSA3341BQX. Verify pin compatibility and electrical specifications before substitution. Note that Fairchild Semiconductor has been acquired by ON Semiconductor; check for updated part numbering or packaging variations.
