Dual 8-bit D-type in a 48-TSSOP footprint
The 74FCT16374ETPAG is a dual 8-bit D-type flip-flop from Renesas Electronics, part of the 74FCT logic family. Each of the two elements stores eight bits, triggered on the positive edge of the clock, with tri-state non-inverted outputs that let multiple devices share a common bus without contention. The 3.7 ns max propagation delay at 5 V and 50 pF load sets the timing budget for high-speed address or data-path pipelines. Combined with 32 mA source and 64 mA sink output drive, this part can fan out to multiple loads on a backplane without external buffers.
Supply, temperature, and package — the fit constraints
Housed in a 48-TFSOP (0.240", 6.10 mm width) package, also designated as 48-TSSOP in the supplier device package field. The 0.50 mm pitch fine-pitch TSSOP footprint is common for high-density logic; verify the PCB land pattern matches the 6.10 mm body width before committing the layout. Quiescent current is 500 µA typ, and input capacitance is 3.5 pF per pin — low enough that the clock-tree driver sees a light load even with all 16 inputs switching.
