SN74SSTV16857DGGR Description

Short technical summary and product information.

The SN74SSTV16857DGGR from Texas Instruments is a 14-bit registered buffer IC, part of the Widebus family. It is engineered for operation within a voltage range of 2.3V to 2.7V, supporting PC1600, PC2100, and PC2700 memory standards, with a specific range of 2.5V to 2.7V for PC3200.

 

This device features SSTL_2 compatible data inputs and outputs, with output edge-control circuitry designed to minimize switching noise in unterminated DIMM loads. It also supports LVCMOS switching levels on its RESET input, which can disable receivers, reset registers, and force outputs low. The flow-through architecture is optimized for PCB layout.

 

Key electrical characteristics include 14 bits of buffering, ESD protection up to 2000V (HBM), and latch-up performance exceeding 100 mA per JESD 78, Class II. The component operates within a temperature range of 0°C to 70°C.

 

The SN74SSTV16857DGGR is available in a 48-TSSOP package, suitable for surface mounting. Its pinout and functionality are compatible with the JEDEC standard SSTV16857.
