An external resistor (R X) and external capacitor (C X) are required as shown in the Logic Diagram. 2. The value of C X may vary from 0 to any necessary value available. If, however, the capacitor has leakages ap- proaching 3.0 mA or if stray capacitance from either ter- minal to ground is more than 50 pF, the timing equations may not represent the pulse width obtained. 3. The output pulse with (t) is defined as follows: t e KR XCX Ð 1 a 1 RX ( for C X l 103 pF K & 0.34 where: R X is in k X,C X is in pF ti si nn s for C X k 103 pF, see Figure 1. f o rKv sC X see Figure 6. 4. If electrolytic type capacitors are to be used, the following three configurations are recommended: A. Use with low leakage capacitors: The normal RC configuration can be used predictably only if the forward capacitor leakage at 5.0V is less than 3 mA, and the inverse capacitor leakage at 1.0V is less than 5 mA over the operational temperature range. R k 0.6 R X (Max) TL/F/6611–4

Operating Rules (Continued) B. Use with high inverse leakage current electrolytic ca- pacitors: The diode in this configuration prevents high inverse leakage currents through the capacitor by preventing an inverse voltage across the capacitor. The use of this configuration is not recommended with retriggera- ble operation. t & 0.3 RC X TL/F/6611–5 C. Use to obtain extended pulse widths: This configuration can be used to obtain extended pulse widths, because of the larger timing resistor al- lowed by beta multiplication. Electrolytics with high in- verse leakage currents can be used. R k RX (0.7) (h FE Q1) or k 2.5 M X, whichever is the lesser RX (min) k RY k RX (max) (5 k X s RY s 10 k X is recommended) Q1: NPN silicon transistor with h FE requirements of above equations, such as 2N5961 or 2N5962. t & 0.3 RC X TL/F/6611–6 This configuration is not recommended with retriggera- ble operation. 5. To obtain variable pulse width by remote trimming, the following circuit is recommended: TL/F/6611–7 6. Under any operating condition, C X and R X (min) must be kept as close to the circuit as possible to minimize stray capacitance and reduce noise pickup. 7. Input Trigger Pulse Rules (See Triggering Truth Table) TL/F/6611–8 Input to Pin 5(11), (Pin 3(13) e HIGH) Pin 4(12) e LOW t1,t 3 e Min. Positive Input Pulse Width l 40 ns t2,t 4 e Min. Negative Input Pulse Width l 40 ns TL/F/6611–9 Input to Pin 4(12) (Pin 3(13) e HIGH) Pin 5(11) e HIGH 8. The retriggerable pulse width is calculated as shown be- low: tW e t a tPLH e KR X CX # 1 a 1 RX J a tPLH TL/F/6611–10 The retrigger pulse width is equal to the pulse width (t) plus a delay time. For pulse widths greater than 500 ns, t W can be approximated as t. Retriggering will not occur if the retrigger pulse comes within & 0.3 C X (ns) after the initial trigger pulse (i.e., during the discharge cycle). 9. Reset OperationÐAn overriding clear (active LOW level) is provided on each one shot. By applying a LOW to the reset, any timing cycle can be terminated or any new cy- cle inhibited until the LOW reset input is removed. Trigger inputs will not produce spikes in the output when the re- set is held LOW. TL/F/6611–11 10. V CC and Ground wiring should conform to good high frequency standards so that switching transients on V CC and Ground leads do not cause interaction between one shots. Use of a 0.01 to 0.1 mF bypass capacitor be- tween V CC and Ground located near the DM9602 is rec- ommended. *For further detailed device characteristics and output performance, please refer to the NSC one-shot application note, AN-366.
