Working Principles

The CD4047BNSR is a versatile integrated circuit that can operate as a monostable or astable multivibrator and oscillator. In the monostable mode, it generates a single pulse of a fixed duration when triggered. In the astable mode, it produces a continuous square wave with adjustable frequency and duty cycle.

The timing of the pulses or oscillations is determined by an external timing capacitor (CT) and resistor (RT). The control voltage (CV) pin allows for frequency modulation by varying the supply voltage. The outputs Q and Q̅ provide complementary waveforms.
