Functional description
A 0 to 1 transition at input Trg sets output Q.
If output Q = 0, and input Trg is set hi at least for the duration
of T
Q is set accordingly.
The off-delay T is triggered when input Trg returns to 0
before T
Output Q is reset when T
You can output an off-warning signal prior to the expiration
of the off-delay time (T - T
the prewarning time period T
always resets T and the output Q.
