A more detailed view of Figure 2 buffer is shown in Figure 3.
The output pull-down of each internal buffer is set for approximately
0.5 V, while the input threshold of each internal buffer is set about
0.07 V lower, when the output is internally driven low. This prevents
a lock-up condition from occurring.
