Procurement Notes

Verify the manufacturer designation carefully, as this part number is historically associated with Fairchild Semiconductor and Texas Instruments. Confirm that the onsemi variant matches the required pinout and electrical specifications. Request the official datasheet to validate RoHS compliance and packaging details before finalizing procurement orders.

Selection Notes

Select this component when designing circuits requiring multiple parallel data lines to be switched simultaneously. Ensure the system voltage remains within the 2.3 V to 3.6 V operational window. Consider the SOIC-24 package dimensions for PCB layout constraints and verify thermal requirements for the specified operating temperature range.

Part Context

This device belongs to the FST (Fast Switching Technology) family of bus switches. These components are engineered to replace traditional mechanical relays or slower solid-state switches in high-frequency digital applications. The 10-bit configuration allows for efficient management of wide data buses without consuming excessive board space.

Replacement Considerations

Public confirmed substitute part numbers include SN74CBTLV3383DW and FST3384MTCX.
