Procurement Notes

Verify the specific manufacturer designation, as Rochester Electronics also lists this part number alongside Fairchild. Confirm the exact pinout and electrical specifications against the official datasheet from the current supplier to ensure compatibility with your circuit design requirements.

Selection Notes

Select this component when a 10-channel bidirectional data path is required with minimal power consumption. Ensure the application voltage aligns with the device's operational limits and that the TSSOP-24 package fits the available PCB footprint constraints.

Part Context

This integrated circuit belongs to the broader family of high-speed CMOS bus switches. It serves as a critical interconnect solution for managing multiple data lines simultaneously while maintaining signal integrity across different voltage domains in compact electronic assemblies.

Replacement Considerations

Check for equivalents within the same CBT/FST series or other 10-bit bus switches from ON Semiconductor. Verify pin-to-pin compatibility and identical functional specifications before substituting.
