Notes: 1. Input pulse level: 0.8 V to 2.2 V
Input rise time and fall time
≤
20 ns
Timing reference levels: 1.0 V and 2.0 V for input; 0.8 V and 2.0 V for output
2. t
DF
is defined at the point where the output is in the open state and the output level
cannot be read.
3. t
OPW
is defined by the value given in the flowchart.
