Registered bus transceiver, FCT logic — active and orderable
The Infineon CY74FCT163H952CPVC is a registered bus transceiver built on FCT (Fast CMOS TTL-compatible) logic — it latches data on the bus with a register stage, which means the output state holds between clock edges, useful for pipelined or buffered data paths where the bus needs to hold a word for the next cycle. Listed as Active in production, so it remains a valid BOM line for new builds and ongoing production — no last-time-buy clock ticking on this one. Ships in Bulk packaging, which is the tube or tray format — not tape-and-reel, so it is a straightforward pick for bench builds, prototype runs, or small-series production where reel feed is not needed.
What the FCT logic family means for the board
FCT logic is TTL-input-threshold compatible and runs from a 5 V supply — it directly interfaces with legacy 5 V TTL buses without a level translator, and the CMOS output drive gives rail-to-rail swing with fast edge rates. The registered transceiver architecture means the part has a D-type flip-flop on the data path — data written to the bus is stored until the next clock edge, which eliminates timing races on shared buses where multiple drivers contend for the same line.
