2 / 10 page HCF4098B 2/10 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 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 RX = 100KΩ . For power supply variation of ±5% typically , for V DD = 10V and 15V and ±1% typically for V DD = 5V at CX = 1000pF and RX = 5KΩ .
