The HCC/HCF4538B dual precision monostable multivibrator provides stable retriggerable/resettable one-shot operation for any fixedvoltage timing application. An external resistor (RX) and an external capacitor (CX) control the timing and accuracy for the circuit. Adjustment of RX and CX provides a wide range of output pulse widths from the Q and Q terminals. The time delay from trigger input to output transition (trigger propagation delay) and the time delay from reset input to output transition (reset propagation delay) are independent of RX and CX. Precision control of output pulse widths is achieved through linear CMOS techniques. Leading-edge-triggering (+ TR) and trailing-edge-triggering (– TR) inputs are provided for triggering from either edge of an input pulse. An unused + TR input should be tied to VSS. An unused – TR input should be tied to VDD. A RESET (on low level) is provided for immediate termination of the output pulse or to September 1988 PIN CONNECTIONS 1/14 HCC/HCF4538B prevent output pulses when power is turned on. An unused RESET input should be tied to VDD. However, if an entire section of the HCC/HCF4538B is not used, its inputs must be tied to either VDD or VSS (see table 1). In normal operation the circuit triggers (extends the output pulse one period) on the application of each new trigger pulse. For operation in the non-retriggerable mode, Q is connected to – TR when leading-edge triggering (+ TR) is used or Q is connected to + TR when trailingedge triggering (– TR) is used. The time period (T) for this multivibrator can be calculated by : T = RX CX. The min. value of external resistance, RX, is 4KΩ. The max. and min. values of external capacitance, C X, are 100µF and 5nF, respectively.

To Avoid possible device damage in this mode, when CX is ≤0.5 microfarad, a aprotection diode with a 1 Ampere or higher rating (1N5395 or equivalent) and a separate ground return for C X should be provided as shown in Fig. 1 An alternate protection method is shown in Fig. 2, where a 51 Ω current limit resistor is inserted in series with CX. Note that a small pulse width decrease will occour however, and RX must be appropriately increased to obtain the originally desired pulse width.
