Description
This 25-bit 1:1 or 14-bit 1:2 configurable registered buffer is 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 1.8-V CMOS drivers that have been optimized to drive the DDR-II DIMM load. ICSSSTUAF32866C operates from a differential clock (CLK and CLK). Data are registered at the crossing of CLK going high, and CLK going low.

Features
• 25-bit 1:1 or 14-bit 1:2 registered buffer with parity check functionality
• Supports SSTL_18 JEDEC specification on data inputs and outputs
• Supports LVCMOS switching levels on C0, C1, and RESET inputs
• Low voltage operation: VDD = 1.7V to 1.9V
• Drop-in replacement for ICSSSTUA32864
• Available in 96-ball BGA package

Applications
• DDR2 Memory Modules
• Provides complete DDR DIMM solution with ICS98ULPA877A or IDTCSPUA877A
• Ideal for DDR2 400, 533, and 667
