description  
This 26-bit registered buffer is designed for 2.3-V to 2.7-V V  
operation and SSTL_2 input and output levels.  
CC  
Data flow from A to Y is controlled by differential clock (CLK, CLK) inputs, the SSTL_2 output-enable (OE) input,  
and the LVTTL reset (RESET) input. Data are triggered on the positive edge of the positive clock (CLK). The  
negative clock (CLK) must be used to maintain noise margins. When RESET is low, all registers are reset, and  
all outputs are low.  
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.  
The SN74SSTL32877 is characterized for operation from 0°C to 70°C.
