CY74FCT163374 and CY74FCT163H374 are 16-bit registers designed for use as buffered registers in high-speed, low power bus applications. They can be used as two independent 8-bit registers or as a single 16-bit register by connecting the output enable (OE) and clock (CLK) inputs. The outputs are 24-mA balanced output drivers with current limiting resistors to reduce the need for external terminating resistors, and provide for minimal undershoot and reduced ground bounce.
The CY74FCT163374 and CY74FCT163H374 are 16‑bit D‑type registers designed for high‑speed, low‑power bus applications. They feature 24 mA balanced output drivers, bus‑hold on data inputs (H‑variant), and power‑off disable for live insertion.
The devices are offered in TSSOP (19.6‑mil pitch) and SSOP (25‑mil pitch) packages, operate over an industrial temperature range of –40 °C to +85 °C, and provide propagation delays as low as 5.2 ns. Detailed electrical characteristics, package diagrams, and ordering information are included.
