Dropout delay
Functional sequence
1. A FALSE−TRUE transition at nIn_b switches bOut_b = TRUE and resets the timer element.
2. A TRUE−FALSE edge at nIn_b starts the timer element.
3. If the delay time has elapsed, that is set by wDelayTime has elapsed, bOut_b = FALSE,
immediately.

General delay
Functional sequence
1. Any edge/transition at nIn_b resets the timer element, and starts it.
2. After the delay time, that is set by wDelayTime has elapsed, bOut_b = nIn_b.
