Working Principles

The CD4047BMG4 is a CMOS-based integrated circuit that operates as a monostable or astable multivibrator and oscillator. In the monostable mode, it produces a single pulse output of a specific duration when triggered. In the astable mode, it generates a continuous square wave output with adjustable frequency and duty cycle.

The IC utilizes external timing resistors (RB and RA) and an external capacitor (CEXT) to control the timing characteristics of the output waveform. The triggering options can be set to either positive or negative edge triggering, providing flexibility in circuit design.
