Input Trg
Trg
Trg
Trg You trigger the on delay with a positive edge (0 to 1
transition) at input Trg (Trigger).
You trigger the off delay with a negative edge (1 to 0
transition).

The time T
H
is triggered with a 0 to 1 transition at input Trg.
If the status at input Trg is 1 at least for the duration of the configured time T
H
, the output is set
to logical 1 upon expiration of this time (output is on delayed to the input signal).
