74SSTV16859DGGRG4

Specialty Logic Overview

The SN74SSTV16859DGGR is a registered buffer designed for 2.3-V to 2.7-V VCC operation, featuring 13-bit to 26-bit data paths. It supports SSTL_2 Class II compatible outputs and accepts SSTL_2 data inputs, with the exception of an LVCMOS RESET input. The device operates from differential clock inputs (CLK and CLK) and registers data at the crossing of CLK going high and CLK going low. It provides 13 inputs and 26 outputs in a 64-pin TSSOP package.

Specialty Logic Feature Summary

• Supports SSTL_2 data inputs and outputs meeting Class II specifications
• Operates on differential clock inputs for precise data registration
• Includes an LVCMOS reset input that disables receivers and forces outputs low
• Designed for low-power standby operation when reset is active

Specialty Logic Applications

• Stacked DDR DIMMs
• Planar DDR RDIMMs
• Low-power support circuits

Specialty Logic Procurement Notes

Verify the specific ordering suffix matches the required package type and lead finish. Confirm moisture sensitivity level ratings and peak reflow temperatures align with assembly processes. Ensure the component status is listed as active production rather than obsolete or preproduction before finalizing procurement plans.

Specialty Logic Selection Notes

Select this component for designs requiring SSTL_2 compatibility within the specified voltage range. Consider the 64-pin TSSOP package dimensions and thermal impedance characteristics for PCB layout. Evaluate the differential clock requirements and setup/hold times against system timing constraints.

Specialty Logic Part Context

This part belongs to the Texas Instruments Widebus family of logic ICs. It is specifically engineered to support memory applications like DDR DIMMs by providing registered buffering capabilities. The device integrates features optimized for DIMM PCB layout and includes robust ESD protection exceeding standard JESD specifications.

Specialty Logic Replacement Considerations

SN74SSTV16859RGQ8 is an obsolete alternative in a different package.
