The CY74FCT16244TPVCT is a 16-bit non-inverting buffer from Cypress's 74FCT family, organised as four 4-bit elements with independent 3-state output enables. The 48-SSOP package (0.295 inch body width) fits medium-density backplane and memory-interface layouts where board area is constrained but a full 16-bit bus width is needed.
Supply rail and drive — the 5 V-only constraint
If your backplane is 3.3 V, you need a level-shifting buffer or a 74LVT/74LVC family part. The asymmetric drive (32 mA source, 64 mA sink) is typical of 5 V logic: the stronger sink handles capacitive discharge on falling edges, which matters for signal integrity on long traces. For fan-out calculations, treat the source current as the limiting factor unless the bus is terminated to VCC.
Lifecycle and compliance
ROHS3 compliant per the listing, with no lead or restricted substances in the package. No recommended replacement exists because the part is still in active manufacture.
Package and mounting
Supplied in a 48-BSSOP (0.295 inch, 7.50 mm width) surface-mount package. Standard MSL 3 handling applies — bake before reflow if the moisture-barrier bag has been open past the floor-life window.
