Retriggerable Monostable Circuit

The CD 4047 is a low-power monostable and astable multivibrator that requires only an external capacitor and a resistor to produce output pulses.

The CD 4047 integrated circuit (IC) is designed for generating precise timing pulses and can operate in two modes: monostable and astable. In monostable mode, the circuit generates a single output pulse in response to a trigger input, with the duration of the pulse determined by the external resistor and capacitor values. This mode is useful for applications that require a specific time delay.

In astable mode, the CD 4047 continuously oscillates between high and low states, producing a square wave output. The frequency and duty cycle of the output waveform can be adjusted by changing the values of the external resistor and capacitor. This functionality makes the CD 4047 suitable for applications such as clock pulses, tone generation, and light flashers.

The circuit configuration typically involves connecting a resistor (R) and capacitor (C) to the appropriate pins of the IC. For monostable operation, the trigger input is activated briefly to initiate the output pulse, while in astable operation, the circuit continuously switches states based on the RC timing components. The output can drive other digital logic circuits or be used to control devices such as LEDs or relays.

The CD 4047 is characterized by its low power consumption, making it ideal for battery-operated devices. It operates over a wide voltage range, typically from 3V to 15V, which adds to its versatility in various electronic applications. The IC is available in different package types, including dual in-line packages (DIP) and surface mount configurations, facilitating easy integration into different circuit designs.CD 4047 is the low power Monostable / Astable Multivibrator that requires only an external capacitor and a resistor to give the output pulses.
