The CY74FCT163501CPVC is a bus transceiver from the FCT series, designed for bidirectional data flow between two independent buses. It is a logic-level translation and buffering component typically used in backplane, memory-mapped I/O, and processor-to-peripheral interfaces where signal integrity and drive strength matter. The FCT family is known for its high speed and low power relative to bipolar logic, making this part a fit for legacy 5 V tolerant systems or mixed-voltage boards that need a clean bus repeater.
That said, the part is RoHS non-compliant — a flag for any BOM that must meet lead-free assembly requirements. If your design allows tin-lead solder, this part remains a straightforward procurement line.
Bulk packaging — plan for manual handling
That means no automated pick-and-place feeding from a reel; your assembly house will need to handle it as a tube-fed or manual-placement component. For low-volume builds or prototyping this is fine, but for high-volume production you may want to verify the tube quantity and feeder compatibility. Store the tubes in a dry, ESD-safe environment; the plastic carriers can hold moisture if left in high humidity.
