Description

The IDT74SSTUBF32869A is 14-bit 1:2 registered buffer with parity, designed for 1.7 V to 1.9 V VDD operation.

All clock and data inputs are compatible with the JEDEC standard for SSTL_18. The control inputs are LVCMOS. All outputs are 1.8V CMOS drivers optimized to drive the DDR2 DIMM load. They provide 50 more dynamic driver strength than the standard SSTU32864 outputs.

Features

• 14-bit 1:2 registered buffer with parity check functionality

• Supports SSTL_18 JEDEC specification on data inputs and outputs

• 50 more dynamic driver strength than standard SSTU32864

• Supports LVCMOS switching levels on C1 and RESET inputs

• Low voltage operation: VDD = 1.7V to 1.9V

• Available in 150 BGA package

Applications

• DDR2 Memory Modules

• Provides complete DDR DIMM solution with ICS98ULPA877A or IDTCSPUA877A

• Ideal for DDR2 667 and 800
