Working Principles

The CD4047BMT is a CMOS-based IC that operates as a monostable/astable multivibrator and oscillator. In the monostable mode, it produces a single pulse output when triggered by an external signal. The astable mode generates a continuous square wave output. The frequency and duty cycle of the output waveform can be adjusted using external components connected to the control voltage (CV), threshold (THRES), and discharge (DISCH) pins.
