description/ordering information  
This 14-bit registered buffer is designed for 2.3-V to 2.7-V V  
operation.  
CC  
All inputs are SSTL_2, except the LVCMOS reset (RESET) input. All outputs are edge-controlled circuits  
optimized for unterminated DIMM loads and meet SSTL_2 Class I specifications.  
The SN74SSTVF16857 operates from a differential clock (CLK and CLK). Data are registered at the crossing  
of CLK going high and CLK going low.
