These dual resettable, retriggerable one shots have two inputsper function; one which is active high, and one which is active low. This allows the designer to employ either leading-edge or trailing-edge triggering, which is independent of input transition times. When input conditions for triggeringare met, a new cycle starts and the external capacitor is allowed to rapidly discharge and then charge again. Theretriggerable feature permits output pulse widths to beextended. In fact a continuous true output can be maintained by having an input cycle time which is shorter than the output cycle time. The output pulse may then be terminated at any time by applying a low logic level to the RESET pin. Retriggering may be inhibited by either connecting the Q output to an active high input, or the Q output to an active low input.
