Description

General part information

74SSTU32864 Series

This 25-bit 1:1 or 14-bit 1:2 configurable registered buffer is designed for 1.7-V to 1.9-V VCCoperation. In the 1:1 pinout configuration, only one device per DIMM is required to drive nine SDRAM loads. In the 1:2 pinout configuration, two devices per DIMM are required to drive 18 SDRAM loads.

All inputs are SSTL_18, except the LVCMOS reset (RESET)\ and LVCMOS control (Cn) inputs. All outputs are edge-controlled circuits optimized for unterminated DIMM loads and meet SSTL_18 specifications.

The SN74SSTU32864 operates from a differential clock (CLK and CLK\). Data are registered at the crossing of CLK going high and CLK\ going low.
