Output Enable Time Measurement
Output balls 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
(high) is 1.05 V, and V
(nominal) = 2.5 V, V
For V

V
Time t
If multiple balls (such as the data bus) are enabled, the measure-
ment value is that of the first ball to start driving.
