Low Power Monostable/Astable Multivibrator
CD4047BC Low Power Monostable/Astable Multivibrator October 1987 Revised March 2002 CD4047BC Low Power Monostable/Astable Multivibrator General Description Monostable Multivibrator The CD4047B is capable of operating in either the Features monostable or astable mode. It requires an external capac- Positive- or negative-edge trigger itor (between pins 1 and 3) and an external resistor Output pulse width independent of trigger pulse duration (between pins 2 and 3) to determine the output pulse width Retriggerable option for pulse width expansion in the monostable mode, and the output frequency in the astable mode.Long pulse widths possible using small RC components by means of external counter provision Astable operation is enabled by a high level on the astable input or low level on the astable input. The output fre-Fast recovery time essentially independent of pulse quency (at 50% duty cycle) at Q and Q outputs is deter- width mined by the timing components. A frequency twice that of Pulse-width accuracy maintained at duty cycles Q is available at the Oscillator Output; a 50% duty cycle is approaching 100% not guaranteed. Monostable operation is obtained when the device is trig- Astable Multivibrator Features gered by LOW-to-HIGH transition at + trigger input or Free-running or gatable operating modes HIGH-to-LOW transition at − trigger input. The device can be retriggered by applying a simultaneous LOW-to-HIGH50% duty cycle transition to both the + trigger and retrigger inputs.Oscillator output available A high level on Reset input resets the outputs Q to LOW, Q Good astable frequency stability to HIGH. typical= ±2% + 0.03%/°C @ 100 kHz frequency= ±0.5% + 0.015%/°C @ 10 kHz deviation (circuits trimmed to frequency V = 10V DD Features ±10%) Wide supply voltage range: 3.0V to 15V High noise immunity: 0.45 V (typ.)
