9601 DM9601 Retriggerable One Shot June 1989 9601 DM9601 Retriggerable One Shot General Description These retriggerable one shots provide the designer with four inputs two active high and two active low This permits a choice of either leading-edge or trailing-edge triggering independent of input transition times When input conditons for triggering are met a new cycle starts and the external capacitor is rapidly discharged and then allowed to charge again The retriggerable feature allows for output pulse widths to be expanded In fact a continuous true output can be maintained by having an input cycle time which is shorter than the output cycle time Retriggering may be inhibited by tying the Q output to an active low input Features Y Y Y Y Y Y Y Y High speed operation input repetition rate l 10 MHz Flexibility of operation optional retriggering lock-out capability Output pulse width range 50 ns to % Leading or trailing edge triggering Complementary outputs inputs Input clamping
