TEST CONDITIONS
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 out-
put disable time (tDIS) is the difference of tMEASURED and tDECAY,
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,
tDECAY, is dependent on the capacitive load, CL, and the current
load, iL, on the output pin. It can be approximated by the fol-
lowing equation:
tDECAY =
CL × 0.5V
iL
from which
tDIS = tMEASURED – tDECAY
is calculated. If multiple pins (such as the data bus) are dis-
abled, the measurement value is that of the last pin to stop
driving.

Output Enable Time
Output pins are considered to be enabled when that 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 the Output Enable/Disable diagram. If multiple pins (such as
the data bus) are enabled, the measurement value is that of the
first pin to start driving.
