Description of the function
Output Q is set to 1 momentarily with a 0 to 1 transition at input Trg.
At the 1 to 0 transition at input Trg, xLogic retriggers the current time T, and the output
remains set. The output Q is reset to 0 when T
a
reaches the value specified in T (T
a
=T)
(off delay).
A one-shot at input Trg retriggers the time Ta.
You can reset the time Ta and the output via the input R (Reset) before the time Ta has
expired
.
