Functional description
A 0 to 1 transition at input Trg sets the output, and triggers a
time T
a
during which the output remains set.
Output Q is reset to lo (pulse output) when T
a
reaches the
value preset at T (T
a
= T).
The output is immediately reset if there is a 1 to 0 transition
at input Trg before the specified time has expired.
If retentivity is not set, output Q and the expired time are re-
set after a power failure.
