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).
Parameter T T T T
H H H H
is the on delay time for the output (output signal transition
0 to 1).
T T T T
L L L L
is the off delay time for the output (output signal transition
1 to 0).
Retentivity
Retentivity
Retentivity Retentivity on = the status is retentive in memory.
Output Q Q Q Q Q is switched on upon expiration of a configured time T
H
if Trg
is still set. It is switched off again upon expiration of the time
T
L
and if Trg has not been set again.

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).
