The CY74FCT16952ATPVC is a dual 8-bit non-inverting transceiver from Cypress's 74FCT family, with 3-state outputs on both ports. Two independent 8-bit elements let it handle a 16-bit data path or two separate 8-bit buses in one package.
56-pin SSOP — rework and layout notes
Fine-pitch but still hand-reworkable with hot air if you preheat the board and use a wide nozzle. The 56-SSOP has a moderate thermal mass; a 30-second preheat at 150°C before reflow helps avoid pad lifting. No exposed pad, so all heat goes through the leads — keep the soldering iron tip clean and use a chisel bit for the outer rows if touch-up is needed.
Not a full mil-spec part, but the industrial range covers most commercial and light-industrial use without a cost premium.
For BOM planning, there is no imminent obsolescence risk, but as with any 5V logic device, the broader industry trend toward lower voltages means long-term availability is worth tracking.
