Long Duration (tW > N)
In this case, inputs /SR0 and /SR1 are LOW for a
duration, tW, which is longer than time N. When an
input goes LOW, the internal timer starts counting.
After time N, the outputs switch and the timer stops
counting. The input goes HIGH sometime after N
seconds. When the input goes HIGH, the timer resets
and the outputs switch back to their original state after
a propagation delay (see Figure 5).

Description
L
The timer starts counting when both inputs go LOW. After time N, the
outputs switch. When either input goes HIGH, the timer resets and the
outputs switch back to their original state. Both /SR0 and /SR1 need to
be LOW to activate (start) the timer.
