CL INCLUDES JIG CAPACITANCE
Note:
(1) This parameter is tested initially and after a design or process change that affects the parameter.
(2) Output floating (High-Z) is defined as the state when the external data line is no longer driven by the output buffer.
(3) Input rise and fall times (10% and 90%) < 10 ns.
