description
This 26-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 LVCMOS
circuits optimized for unterminated DIMM loads.
The SN74SSTV32867 operates from a differential clock (CLK and CLK). Data are registered at the crossing
of CLK going high and CLK going low.
The device supports low-power standby operation. When RESET is low, the differential input receivers are
disabled, and undriven (floating) data, clock, and reference voltage (VREF) inputs are allowed. In addition, when
RESET is low, all registers are reset and all outputs are forced low. The LVCMOS RESET always must be held
at a valid logic high or low level.
To ensure defined outputs from the register before a stable clock has been supplied, RESET must be held in
the low state during power up.
