Additional Details

The IDT74SSTV16857PA typically operates at 3.3V. The 'PA' suffix likely refers to the package type, often a TSSOP (Thin Shrink Small Outline Package) or similar surface mount package. Detailed timing specifications (e.g., propagation delays) are usually available in the IDT datasheet. The component is designed to meet JEDEC standards for registered buffer operation. It is typically used in conjunction with DRAM chips to form registered DIMMs. Its function is critical in achieving large and reliable memory configurations in high-performance computing environments. Specifically, registered buffers help to reduce the load on the memory controller and thus permit larger memory configurations without compromising the signal integrity, which is crucial for proper operation.
