Output Enable Time Measurement
Output signals are considered to be enabled when they have
made a transition from a high impedance state to the point
when they start driving.
The output enable time t
a reference signal reaches a high or low voltage level to the point
when the output starts driving as shown on the right side of
Figure
The time t
signal switches to when the output voltage reaches V
or V
V
val from when the output starts driving to when the output
reaches the V
Time t
If multiple signals (such as the data bus) are enabled, the mea-
surement value is that of the first signal to start driving.
