Description:
The positive edge at input 1 is transferred to the output after delay t1, the negative edge after
delay t2. The delay time starts again with each edge.
TRUE at the Superior Set input sets the output to TRUE. TRUE at the Superior Reset input sets
the output to FALSE.
Via the output buffer, the output signal is globally available.
Inputs Superior Set and Superior Reset are connected in series with the function. Levels at in-
put I1 are processed internally. As soon as the Superior Set or Superior Reset is reset, the out-
put is switched to the internally saved value.
