Functional description
The 0 to 1 transition at input En triggers a random on-delay
time between 0 s and T
H
. The output is set when the on-de-
lay time has expired and if the signal at input En remains hi
at least for the duration of this time.
The time is reset if input En is reset before the on-delay time
has expired.
A 1 to 0 transition at input EN triggers a random on-delay
time between 0s and T
L
.
The output is reset after the off-delay time has expired, pro-
vided input En remains lo at least for the duration of this time.
The time is reset if the signal at input En changes to 1 again
before the off-delay time has expired.
The time expired is reset after a power failure.
