74SSTV16857PAG

Specialty Logic Overview

The 74SSTV16857PAG is a 14-bit registered buffer manufactured by Renesas Electronics Corporation. It operates within a supply voltage range of 2.3V to 2.7V and supports SSTL_2 Class II data inputs and outputs. The device features differential clock inputs and an LVCMOS-compatible reset control. Designed for DDR memory applications, it provides flow-through architecture for optimal PCB design and drives up to the equivalent of 18 SDRAM loads. The component is housed in a 48-pin TSSOP package.

Specialty Logic Procurement Notes

Verify current availability status as this component may be discontinued or obsolete. Confirm package type and pinout compatibility with existing designs. Check for RoHS compliance documentation. Ensure sourcing from authorized distributors to guarantee authenticity. Review manufacturer notices for any lifecycle changes or replacement recommendations.

Specialty Logic Selection Notes

Select this component for legacy DDR memory designs requiring 14-bit buffering. Ensure system voltage aligns with the 2.3V-2.7V operating range. Verify that the TSSOP-48 package fits the board layout constraints. Consider end-of-life status when planning long-term production runs. Evaluate alternative parts if new design support is required.

Specialty Logic Part Context

This part belongs to the SSTVF/SSTV logic series designed for high-speed memory interfaces. It serves as a registered buffer to isolate memory controllers from memory banks. The 14-bit width matches common DDR data bus configurations. It is distinct from standard logic families due to its specific SSTL termination requirements.

Specialty Logic Replacement Considerations

SSTVA16857A is a pin-to-pin compatible alternative. SN74SSTV16857DGVRG is a similar function from Texas Instruments but uses a TVSOP package. Verify electrical characteristics and package dimensions before substitution.
