Procurement Notes

Verify the specific suffix 'MEA' corresponds to the 56-SSOP package configuration when sourcing. Confirm RoHS compliance status as indicated in official documentation. Ensure the supplier provides genuine Fairchild Semiconductor components to guarantee performance parameters such as the 14 Ohm on-resistance and 250 ps propagation delay are met. Cross-reference datasheets for exact pinout definitions.

Selection Notes

Select this component for designs requiring 24-bit parallel data path reconfiguration. The 56-SSOP package suits space-constrained PCB layouts. Consider the 5 V operating voltage requirement against system power rails. The low propagation delay makes it suitable for timing-critical interfaces where signal integrity across multiple buses is essential.

Part Context

This part belongs to the FST series of bus switches, designed for high-performance digital applications. It serves as a critical interconnect solution in complex electronic systems, allowing dynamic reconfiguration of data paths. The device integrates multiple independent switches into a single IC, reducing board space compared to discrete solutions.

Replacement Considerations

Consult official substitution guides for equivalent parts from Onsemi or other manufacturers. Verify pin compatibility and electrical characteristics before swapping. No direct substitute part numbers are confirmed in public documentation without further verification.
