Notes: 1. Input pulse level: 0.8 V to 2.2 V
Input rise time/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 at the point at which the output is floating and the output level cannot be
read.
3. t_OPW is defined by the value given in figure 6.4 high-performance programming flow
chart.
