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 i a choice of either leading-edge or trailing-edge triggering ndependent 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 C

Operating Rules
1 An external resistor RX and an external capacitor CX are required for operation The value of RX can vary between the limits shown in switching characteristics The value of CX is optional and may be adjusted to achieve the re2 quired output pulse width Output pulse width tPW may be calculated as follows t 07 a (for CX l 103 pF) PW e K RXCX RX 0 34 K ( X in kX CX in pF and tPW in ns R For CX k 103 pF see curve ) 3 RX and CX must be kept as close as possible to the circuit in order to minimize stray capacitance and noise pickup If remote trimming is required RX may be split up such that at least RX(MIN) must be as close as possible to the circuit and the remote portion of the trimming re4 sistor R k RX(MAX) b RX 5 Retrigger pulse width (see Figure 3 ) is calculated as folt lows
