CD4047 - Monostable : Astable Multivibrator DIP IC

CD4047B CMOS Monostable/Astable Multivibrator DIP IC

The CD4047B is a highly versatile CMOS integrated circuit designed for both monostable (one-shot) and astable (free-running) multivibrator operations. This DIP IC simplifies the creation of timing circuits and signal generators. Users can easily determine the output pulse width in monostable mode or the output frequency in astable mode. This is achieved by connecting just an external capacitor and resistor. Astable operation offers a 50% duty cycle at Q and Q outputs, with a double frequency available at the Oscillator Output. Monostable mode is triggered by either a LOW-to-HIGH or HIGH-to-LOW transition. The device also supports retriggering for extended pulse generation. Its robust design ensures reliable performance across various applications. This makes it an essential component for hobbyists and professional engineers alike.
