Output Disable Time
Output pins are considered to be disabled when they have stopped driving and started a transition from
the measured output high or low voltage to a high impedance state. The output disable time (t
DIS
) is the
difference of t
MEASURED
and t
DECAY
, as shown in the Output Enable/Disable diagram. The time is the
interval from when a reference signal reaches a high or low voltage level to when the output voltages
have changed by 0.5 V from the measured output high or low voltage.
The decay time, t
DECAY
, is dependent on the capacitive load, CL, and the current load, iL, on the output
