The IDT74SSTV16859PAG8 is a 14-bit to 28-bit Registered Buffer with SSTL_2 inputs and outputs, manufactured by IDT (Integrated Device Technology). It is specifically designed for high-speed memory applications, such as DDR2 Registered DIMMs (RDIMMs), where signal integrity and reliable data transfer are critical.

Applications:

• DDR2 Registered DIMMs (RDIMMs): Used as a registered buffer in DDR2 RDIMMs to improve signal integrity and increase memory capacity.
• Memory Modules: Buffering signals between memory controllers and DRAM chips in memory modules.
• High-Speed Data Transfer: Applications requiring high-speed data transfer with minimal signal degradation.

Features:

• 14-Bit to 28-Bit Registered Buffer: Buffers 14 input bits to 28 output bits for improved signal driving.
• SSTL_2 Inputs and Outputs: Compliant with SSTL_2 (Stub Series Terminated Logic for 2.5V) signaling standards.
• Registered Architecture: Includes registers to synchronize data transfer and improve timing margins.
• Low Propagation Delay: Minimizes latency for high-speed memory access.
• Low Power Consumption: Designed for efficient power usage in memory applications.
• 3-State Outputs: Outputs can be in a high, low, or high-impedance state.
• Available in TSSOP Package: Offers a compact surface-mount package.

Benefits:

• Improved Signal Integrity: Buffering reduces noise and signal degradation, ensuring reliable data transfer.
• Increased Memory Capacity: Enables larger memory capacities by improving signal quality on the memory bus.
• Enhanced System Performance: High-speed operation minimizes latency and maximizes memory bandwidth.
