74SSTUB32865A Overview
This 28-bit 1:2 configurable registered buffer is designed for 1.7-V to 1.9-V VCC operation. One device per DIMM is required to drive up to stacked 18 SDRAM loads or two devices per DIMM are required to drive up to 36 stacked SDRAM loads. All inputs are SSTL_18, except the chip-select gate-enable (CSGateEN) and reset (RESET) inputs, which are LVCMOS.
