L64734 AC Timing
36
Table 10
This section includes AC timing information for the L64734. During AC
testing, HIGH inputs are driven to 3.0 V, and LOW inputs are driven to
0 V. For transitions between HIGH, LOW, and invalid states, timing
measurements are made at 1.5 V, as shown in
Figure 8
Output
For 3-state outputs, timing measurements are made from the point at
which the output turns ON or OFF. An output is ON when its voltage is
greater than 2.5 V or less than 0.5 V. An output is OFF when its voltage
is less than V
