The IDT74SSTV16857PA8 is a 14-bit to 28-bit registered buffer with SSTL_2 outputs, manufactured by Renesas Electronics (formerly IDT). It's primarily used in memory modules, particularly DDR2 SDRAM, to improve signal integrity and drive capability on heavily loaded memory buses.

Applications

• DDR2 SDRAM memory modules
• Server memory
• Workstation memory
• High-performance computing systems

Features

• 14-bit input to 28-bit output buffering
• SSTL_2 output signaling
• Registered outputs
• Low propagation delay
• 3.3V power supply
• TSSOP package

Benefits

• Improves signal integrity in DDR2 memory systems.
• Increases drive capability, allowing for more memory modules on a bus.
• Reduces loading on the memory controller.
• Ensures reliable data transfer at high speeds.
• Minimizes signal skew.
• Small package size allows for compact memory module designs.

Technical Specifications

The IDT74SSTV16857PA8 typically has the following specifications:

• Supply Voltage: 3.3V
• Data Rate: Up to DDR2 specifications (e.g., 800 MHz)
• Propagation Delay: Low nanosecond range
• Operating Temperature: Industrial temperature range (e.g., -40°C to +85°C)
• Package Type: TSSOP (Thin Shrink Small Outline Package)

This registered buffer is a key component in high-performance DDR2 memory systems, ensuring reliable operation even with a large number of memory modules. Its SSTL_2 outputs are specifically designed to meet the requirements of DDR2 signaling.
