With the input signal Trg = 1, output Q is set to 1. The signal also triggers the time Ta, while the
output remains set.
When Ta reaches the value defined at T (Ta=T), the output Q is reset to 0 state (pulse output).
If the signal at input Trg changes from 1 to 0 before this time has expired, the output is
immediately reset from 1 to 0.
