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 where the external data line is no longer driven by the output buffer.
(3) Input Rise and Fall Times (10% to 90%) < 10 ns.
(4) Input Pulse Levels = 0.45V and 2.4V.
(5) Input and Output Timing Reference = 0.8V and 2.0V.
(6) Low-Z is defined as the state where the external data may be driven by the output buffer but may not be valid.
