9601中文资料Retriggerable One Shot数据手册TI规格书

描述 Description

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.
