K4S56323PF-F(H)G/F
AC CHARACTERISTICS
NOTES :
1. Parameters depend on programmed CAS latency.
2. If clock rising time is longer than 1ns, (tr/2-0.5)ns should be added to the parameter.
3. Assumed input rise and fall time (tr & tf) = 1ns.
CLK cycle time
CLK to valid output delay
Output data hold time
CLK high pulse width
CLK low pulse width
Input setup time
Input hold time
CLK to output in Low-Z
CLK to output in Hi-Z
If tr & tf is longer than 1ns, transient time compensation should be considered,
i.e., [(tr + tf)/2-1]ns should be added to the parameter.
