SN74SSTVF16859SR

Specialty Logic Overview

The SN74SSTVF16859SR is a registered buffer designed for PC1600, PC2100, and PC2700 applications operating at 2.3 V to 2.7 V. It features 13-bit to 26-bit data width with differential clock inputs (CLK and CLK). The device supports SSTL_2 Class I outputs and LVCMOS switching on the RESET input. It includes output edge-control circuitry to minimize switching noise in unterminated lines.

Specialty Logic Feature Summary

• Supports simultaneous switching performance exceeding JEDEC standard SSTV16859 by 600 ps in PC2700 DIMM applications.
• Provides 1-to-2 output configuration capability to support stacked DDR DIMMs.
• Integrates output edge-control circuitry specifically optimized to minimize switching noise in unterminated line loads.

Specialty Logic Applications

• PC1600, PC2100, and PC2700 memory modules
• Stacked DDR DIMM architectures
• Registered buffer interfaces for high-speed data transmission
