| CD4047BC Low Power Monostable/Astable Multivibrator CD4047BC Low Power Monostable/Astable Multivibrator The 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 + trigger input or HIGH-to-LOW transition at − trigger input. The device can be retriggered by applying a simultaneous LOW-to-HIGH transition to both the + trigger and retrigger inputs. A high level on Reset input resets the outputs Q to LOW, Q to HIGH. s Wide supply voltage range 3.0V to 15V s High noise immunity VDD typ. s Low power TTL compatibility Fan out of 2 driving 74L or 1 driving 74LS Special Features s Low power consumption special CMOS oscillator configuration s Monostable one-shot or astable free-running operation s True and complemented buffered outputs s Only one external R and C required Monostable Multivibrator Features s Positive- or negative-edge trigger s Output pulse width independent of trigger pulse duration s Retriggerable option for pulse width expansion s Long pulse widths possible using small RC components by means of external counter provision s Fast recovery time essentially independent of pulse width s Pulse-width accuracy maintained at duty cycles approaching 100% Astable Multivibrator Features s Free-running or gatable operating modes s 50% duty cycle s Oscillator output available s Good astable frequency stability typical= ±2% + 0.03%/°C 100 kHz frequency= + 0.015%/°C 10 kHz deviation circuits trimmed to frequency VDD = 10V ±10% • Frequency discriminators • Timing circuits • Time-delay applications • Envelope detection • Frequency multiplication • Frequency division Ordering Code: Order Number Package Number Package Description CD4047BCM M14A 14-Lead Small Outline Integrated Circuit SOIC , JEDEC MS-012, Narrow CD4047BCN N14A 14-Lead Plastic Dual-In-Line Package PDIP , JEDEC MS-001, Wide Devices also available in Tape and Reel.
