Description
SN74ALVCH16825DGGY is a TI dual 8-bit storage/register device from the ALVCH family. It provides 16 bits of storage across two 8-bit registers and 3-state outputs for bus interfacing.
Key points:
- Two 8-bit storage registers sharing a common clock; data presented on outputs when enabled.
- 3-state outputs controlled by an output-enable input.
- Input-bus hold on each input for bus stability.
- Supply voltage ~1.65 V to 3.6 V (low-voltage CMOS).
- Fast, low-power operation suitable for buffering/latching data on data or address buses.
- Packaging: DGGY denotes TI’s 16-pin TSSOP/VSSOP-style package.
Typical use: act as a data bus buffer, temporary storage/latch for microprocessor/miser peripheral buses, or interface between logic domains needed by a CPU or FPGA.

Application
74ALVCH16825DGGY is a 16‑bit register with tri‑state outputs (low‑voltage CMOS). Typical application areas include:
- Microprocessor/Microcontroller bus interfacing and I/O expansion
- Data buffering and temporary storage for memory‑mapped I/O and FIFO paths
- Driving or buffering a shared data bus with tri‑state control to isolate devices
- Word‑wide data transfer between ASIC/FPGA subsystems and peripherals
- System integration in mixed‑voltage environments (low‑voltage operation)
In short: use for fast, bus‑oriented data storage and reliable bus sharing in digital designs.
