SN74SSTVF16859S8

Specialty Logic Overview

The SN74SSTVF16859S8 is a registered buffer from the Texas Instruments SN74SSTVF series, designed for high-speed memory applications. It features 13 to 26-bit data width and operates with SSTL_2 compatible I/O levels suitable for DDR ICs. The device functions within a supply voltage range of 2.3 V to 2.7 V and supports an operating temperature range of 0°C to 70°C. It is housed in a 56-VQFN (8x8) package.

Specialty Logic Feature Summary

• Provides registered buffering with configurable 13 or 26-bit data widths
• Features SSTL_2 compatible I/O optimized for DDR interface requirements
• Utilizes edge-controlled LVCMOS output circuits designed for unterminated DIMM loads

Specialty Logic Applications

• Registered Dual In-line Memory Modules (RDIMMs)
• Stacked Low-Profile (1U) PC-1600/2100 DIMMs
• Planar PC2700 (DDR-333) RDIMMs

Specialty Logic Procurement Notes

Verify the specific package variant, as the S8 suffix denotes the 56-VQFN form factor. Confirm that the design environment strictly adheres to the 2.3 V to 2.7 V supply voltage constraints. Ensure thermal management aligns with the 0°C to 70°C commercial operating range. Cross-reference the datasheet revision to confirm pinout compatibility with existing PCB layouts before finalizing procurement.

Specialty Logic Selection Notes

Select this component when designing systems requiring SSTL_2 signaling standards for DDR memory interfaces. It is appropriate for applications needing registered buffering with flexible 13 or 26-bit configurations. Consider the 56-VQFN package for space-constrained designs requiring surface-mount technology. Ensure the system clock and power delivery meet the specific electrical characteristics defined in the official technical documentation.

Specialty Logic Part Context

This part belongs to the SN74SSTVF logic family, which focuses on low-power support for high-speed memory systems. It complements other components like the SN74SSTV16859DGGR, differing primarily in packaging and specific interface optimizations.
