Notes: 1. Input pulse level: 0.8 V to 2.2 V
Input rise time and fall time ≤ 20 ns
Timing reference levels: Input: 1.0 V, 2.0 V
Output: 0.8 V, 2.0 V
2. t_DF is defined to be when output has reached the open state, and the output level can no
longer be referenced.
3. t_OPW is defined by the value shown in the flowchart.
