CD4047 CMOS Low Power Monostable/Astable Multivibrator IC DIP-14 Package IC

- 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.
