Timing diagram
Description of the function
With the 0 to 1 transition at input En, a random time (on delay time) between 0 s and T
H
is set and triggered.
If the status at input En is 1 at least for the duration of the on delay, the output is set to 1 when this on delay
time has expired.
The time is reset if the status at input En is reset to 0 before the on delay time has expired.
When input En is reset 0, a random time (off delay time) between 0 s and T
L
is set and triggered.
If the status at input En is 0 at least for the duration of the off delay time, the output Q is reset to 0 when the
off delay time has expired.
The time is reset if the status at input En returns to 1 before the on delay time has expired.
