National Semiconductor CD4047BM
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...| Part No. | CD4047BM |

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 MONOSTABLE MULTIVIBRATORFEATURES
