4047 CD4047BE 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 isnot 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.

Feature:

  • Monostable (one-shot) or Astable (free-running) Operation
  • Oscillator Input Available
  • True and Complemented Buffered Outputs
  • Operating Temperature to 85oC
  • Low Power TTL
