Product Name: DDR-II

Product Description

Texas Instruments introduces the SN74SSTU32864 enabling the industry for DDR-II RDIMMs. While competitors are still focusing on back filling their DDR-I portfolio, TI again takes the leadership role by being ahead of the market with this register targeted at next generation DDR-II systems. The SN74SSTU32864 is the world's first DDR-II register that employs output edge control circuitry similar to the technology used in our already successful SSTVF product line. It has proven simultaneous switching performance in initial prototype DDR-II RDIMMs, enabling high speeds without sacrificing signal integrity. This device is configurable as a 1:1 or 1:2 registered buffer, which makes it flexible enough to be used in a multitude of RDIMM configurations. 

TI also offers the SN74SSTU32866 for higher reliability systems. This register has the capability of adding parity to a DDR-II RDIMM. Additional parity I/Os are introduced to for the parity calculation. When two devices are used on a DIMM, the register has the capability of cascading the parity path of the two registers while maintaining the same parity output timing as the single device parity configuration. 

SSTU family features: 
Operates at 1.7 V to 1.9 V for PC2-3200 and PC2-4300
Pinout Optimizes DDR-II DIMM PCB Layout
Chip-Select Inputs Gate the Data Outputs from Changing State and Minimizes System Power Consumption
Output Edge-Control Circuitry Minimizes Switching Noise in an Unterminated Line
Parity Option Available
