SN74SSTVF16859GR

Specialty Logic Overview

The SN74SSTVF16859GR is a CMOS registered buffer from the SSTVF logic series, housed in a 64-TSSOP package. It operates 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. The device features 13 inputs and 26 outputs, providing a propagation delay of 2.5 ns. Output drive capabilities include a low-level current of 16 mA and a high-level current of -16 mA.

Specialty Logic Feature Summary

• Configurable as a 13-bit or 26-bit registered buffer for flexible data path management
• Designed with SSTL_2 compatible DDR I/O interfaces for memory system integration
• Provides registered buffering functionality to support high-speed signal integrity

Specialty Logic Applications

• Application in stacked low-profile (1U) PC-1600/2100 DIMMs
• Implementation in planar PC2700 (DDR-333) RDIMMs
• Low-power support configurations using Texas Instruments SN74SSTV16857 and SN74SSTV16859 families

Specialty Logic Procurement Notes

Verify the specific suffix 'GR' corresponds to the TSSOP-64 package variant when sourcing. Confirm that the component meets RoHS requirements and check moisture sensitivity levels prior to assembly. Ensure the ordering quantity aligns with the manufacturer's standard packaging multiples to avoid partial reel issues during procurement.

Specialty Logic Selection Notes

Select this component for designs requiring SSTL_2 compatibility and registered buffering within the specified 2.3 V to 2.7 V voltage window. Consider the 64-TSSOP footprint for surface mount applications. Evaluate the 2.5 ns propagation delay against system timing constraints to ensure adequate performance for the target DDR memory interface speeds.
