Working Principles

The CD4047BPWR is a versatile IC that can operate in monostable or astable mode. In monostable mode, it produces a single pulse output when triggered by an external signal. In astable mode, it generates a continuous square wave output. The frequency of the output waveform is determined by the values of the timing resistor (RT) and timing capacitor (CT). The control voltage (CV) input allows frequency modulation of the output waveform. The IC also features a reset function for manual resetting of the circuit.
