s and T
H
.
TL:
The off delay is determined at random and lies between 0
s and T
.
Output
Q is set on expiration of the on delay if En is still set. It is reset
when the off delay time has expired and if En has not been set
again.

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.
