CD4047BM/CD4047BC Low Power Monostable/Astable Multivibrator General Description CD4047B is capable of operating in either the monostable or astable mode. It requires an external capacitor (between pins 1 and 3) and an external resistor (between pins 2 and 3) to determine the output pulse width in the monostable mode, and the output frequency in the astable mode. Astable operation is enabled by a high level on the astable input or low level on the astable input. The output frequency (at 50% duty cycle) at Q and Q outputs is determined by the timing components. A frequency twice that of Q is available at the Oscillator Output; a 50% duty cycle is not guaranteed. Monostable operation is obtained when the device is triggered by low-to-high transition at a trigger input or high-tolow transition at b trigger input. The device can be retriggered by applying a simultaneous low-to-high transition to both the a trigger and retrigger inputs. A high level on Reset input resets the outputs Q to low, Q to high.
