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 (tDIS) is the difference of tMEASURED and tDECAY, as
shown in Figure 20. The time is the interval from when a refer-
ence signal reaches a high or low voltage level to when the
output voltages have changed by 0.5 V from the measured out-
put high or low voltage.
The decay time, tDECAY, is dependent on the capacitive load, CL,
and the current load, iL, on the output pin. It can be approxi-
mated by the following equation:
from which
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 (tENA) 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 20. If multiple pins (such as the data bus) are enabled,
the measurement value is that of the first pin to start driving.
