Output Disable Time
Output pins are considered to be disabled when they have
stopped driving and started a transition from the measured out-
put 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 Figure 13. The time t
MEASURED
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 mea-
sured output high or low voltage.
The decay time, t
DECAY
, is dependent on the capacitative load,
C
L
, and the current load, i
L
, on the output pin. It can be ap-
proximated by the following equation:

is calculated. If multiple pins (such as the data bus) are disabled,
the measurement value is that of the last pin to stop driving.
Output Enable Time
Output pins are considered to be enabled when they have made
a transition from a high-impedance state to when they start
driving. The output enable time (t
ENA
) is the interval from when
a reference signal reaches a high or low voltage level to when the
output has reached a specified high or low trip point, as shown
in Figure 13. If multiple pins (such as the data bus) are enabled,
the measurement value is that of the first pin to start driving.
