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 as when output reaches the release state and the output level could not
be referenced.
3. t_OPW is defined as the value given in the flowchart.
