Notes: 1. Input pulse level: 0.45 V to 2.4 V
Input rise time/fall time
≤
20 ns
Timing reference levels: Input:
0.8 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 the hi-speed, hi-reliability programming flow chart in
figure 6.4.
