SSTVA16857AGLFT

Specialty Logic Overview

The SSTVA16857AGLFT 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 applications, 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. It supports low standby operation and drives up to the equivalent of 18 SDRAM loads. The component is housed in a 48-pin TSSOP package.

Specialty Logic Procurement Notes

This component is officially classified as obsolete and no longer in production. Availability is restricted to existing stock from authorized distributors or secondary market sources. Verification of authenticity and physical condition is critical when sourcing end-of-life parts. Ensure that any acquired units match the specific GLFT suffix for reel packaging and lead-free status before integration into designs.

Specialty Logic Selection Notes

Designers should note that this part is not recommended for new designs due to its obsolete status. Consider evaluating alternative components with current manufacturing support if starting a new project. Existing designs utilizing this buffer must plan for long-term supply chain risks associated with end-of-life products. Verify pin-to-pin compatibility requirements carefully against potential replacement options.
