description/ordering information
This 14-bit registered buffer is designed for 2.3-V to 2.7-V VCC operation.
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.
