CD4098B dual monostable multivibrator provides stable retriggerable/resettable one-shot operation for any fixed-voltage timing application.

An external resistor (R_X) and an external capacitor (C_X) control the timing for the circuit. Adjustment of R_X and C_X provides a wide range of output pulse widths from the Q and Q\ terminals. The time delay from trigger input to output transition (trigger progagation delay) and the time delay from set input to output transition (reset progagation delay) are independent of R_X and C_X.

Leading-edge-triggering (+TR) and trailing-edge-triggering (-TR) input are provided for triggering from either edge of an input pulse. An unused +TR input should be tied to V_SS. An unused (-TR) input should be tied to V_DD. A RESET (on low level) is provided for immediate termination of the output pulse or to prevent output pulses when power is turned on. An unused RESET input should be tied to V_DD. However, if an entire section of the CD4098B is not used, its RESET should be tied to V_SS. 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 trailing-edge triggering (-TR) is used.

The time period (T) for this multivibrator can be approximated by: T_X= ½ R_XC_X for C_X 0.01 uF. Time periods as a function of R_X for values of C_X and V_DD are given in Fig. 8. Values of T vary from unit to unit and as a function of voltage, temperature, and R_XC_X.

The minimum value of external resistance, R_X, is 5 k. The maximum value of external capacitance, C_X, is 100uF. Fig.9 shows time periods as a function of C_X for values of R_X and V_DD.

The output pulse width has variations of ±2.5% typically, over the temperature range of -55°C to 125°C for C_X= 1000 pF and R_X= 100 k.

For power supply variations of ±5%, the output pulse width has variations of ±0.5% typically, for V_DD= 10 V and 15 V and ±1% typically, for V_DD= 5 V at C_X= 1000 pF and R_X= 5 k.

These types are supplied in 16-lead hermetic dual-in-line ceramic packages (F3A suffix), 16-lead dual-in-line plastic package (E suffix), 16-lead small-outline packages (M, M96, and MT suffixes), and 16-lead thin shrink small-outline packages (PW and PWR suffixes).

The CD4098B is similar to type MC14528.
