The dual multivibrator
is
shown in Figure
4
-
17.
The
pits
are retriggerable and resettable
multivibrators which provide an output pulse whose duration
is
a
function of the external timing
components. The inputs are dc level sensitive;
i.e., triggering occurs on the rising or trailing
edges of the input waveform. Successive inputs with
a
period shorter than the delay time will
retrigger the one
-
shot resulting in
a
continuous true output. The output pulse may be terminated
at
any time by applying
a
low logic level to the reset input.
