The HCF4098B dual precision monostable multivibrator provides stable retriggerable/ resettable one-shot operation for any fixed voltage timing application. An external resistor (RX) and an external capacitor (CX) control the timing for the circuit. Adjustment of RX and C X provides a DIP SOP ORDER CODES PACKAGE TUBE T&R DIP SOP HCF4098BEY HCF4098BM1 HCF4098M013TR 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) and the time delay from reset input to output transition (reset propagation delay) are independent of RX and CX. 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 prevent output pulses when power is turned on. PIN CONNECTION September 2001 1/10 HCF4098B An unused RESET input should be tied to VDD . However, if an entire section of the HCF4098B is not used, its reset should be tied to 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-retiggerable mode, Q is connected to -TR when leading edge triggering (+TR) is used or Q is connected to +TR when trailing edge triggering (-TR) is used. The time period (T) for this IINPUT EQUIVALENT CIRCUIT multivibrator can be calculated by : T = 1/2 RX CX for CX > 0.01µF. The min. value of external resistance, RX, is 5KΩ. The max. values of external capacitance, CX, is 100 µF. The output pulse width has variations of ±2.5% typically, over the temperature range of -55 °C to 125 °C for CX=1000pF and R X = 100KΩ . For power supply variation of ±5% typically , for V DD = 10V and 15V and ±1% typically for VDD = 5V at CX = 1000pF and RX = 5KΩ .
