This parameter is tested initially and after a design or process change that affects the parameter.
Output floating (High-Z) is defined as the state where the external data line is no longer driven by the output buffer.
Input Rise and Fall Times (10% to 90%) < 10 ns.
Input Pulse Levels = 0.45 V and 2.4 V. For High Speed Input Pulse Levels 0.0 V and 3.0 V.
Input and Output Timing Reference = 0.8 V and 2.0 V. For High Speed Input and Output Timing Reference = 1.5 V.
Low-Z is defined as the state where the external data may be driven by the output buffer but may not be valid.
For load and reference points, see Fig. 1.
