SSTVF16857AGLFT/M

Specialty Logic Overview

The SSTVF16857AGLFT is a 14-bit registered buffer manufactured by Renesas Electronics. It operates within a voltage range of 2.3V to 2.7V for PC1600, PC2100, and PC2700 specifications, and 2.5V to 2.7V for PC3200. The device features SSTL_2 Class II compatible data inputs and outputs, a differential CLK input, and LVCMOS-compatible RESET control. Packaged in a 48-TSSOP with a lead count of 48, it supports low standby operation and drives up to the equivalent of 18 SDRAM loads.

Specialty Logic Feature Summary

• Features a flow-through architecture designed for optimum PCB layout efficiency.
• Includes differential clock input and reset control compatible with LVCMOS levels.

Specialty Logic Applications

• DDR memory systems supporting PC1600, PC2100, and PC2700 speeds
• DDR memory systems supporting PC3200 speeds
• Registered buffer circuits requiring SSTL_2 I/O compatibility

Specialty Logic Procurement Notes

This component is classified as obsolete and not recommended for new designs. Availability is restricted, with current stock status indicating out-of-stock conditions across major distributors. Verification of end-of-life status and final time buys is essential before integration into any production roadmap due to discontinued manufacturing status.

Specialty Logic Selection Notes

Engineers should consider this part only for maintenance or legacy system repairs where pin-to-pin compatibility with SSTV16857 or SSTVN16857 is required. New designs must avoid this component due to its obsolete status. Alternative modern registered buffers from the manufacturer's active portfolio should be evaluated for long-term supply chain stability and updated feature sets.

Specialty Logic Part Context

The SSTVF16857AGLFT belongs to the SSTVA16857A series of DDR registered buffers. It is functionally related to the SSTV16857 and SSTVN16857 models, adhering to similar JEDEC standards. The device is categorized under logic ICs and serves as a critical interface component for synchronizing data signals in high-speed DDR memory architectures using TSSOP packaging.

Specialty Logic Replacement Considerations

Pin-to-pin compatible alternatives include the SSTV16857 and SSTVN16857. However, these counterparts are also listed as obsolete. Designers should consult Renesas for current active replacements suitable for new designs, as direct substitutes may require schematic adjustments despite package compatibility.
