Notes: 1. Input pulse level: 0.45–2.4 V
Input rise, fall time ≤ 20 ns
Input timing reference levels: 0.8 V, 2.0 V
Output timing reference levels: 0.8 V, 2.0 V
2. t_DF is defined at the point where the output is in the open state and the output level
cannot be referenced.
3. t_OPW is defined by the value given in the flowchart.
