CD4047 - Astable/Monostable Multivibrator IC

CD4047 IC consists of a gateable astable multivibrator with logic techniques incorporated to permit positive or negative edge-triggered monostable multivibrator action with retriggering and external counting options.

Inputs include +TRIGGER, -TRIGGER, ASTABLE, ASTABLE\, RETRIGGER, and EXTERNAL RESET. Buffered outputs are Q\, Q an OSCILLATOR. In all modes of operation, an external capacitor must be connected between C-Timing and RC-Common terminal, and an external resistor must be connected between the R-Timing and RC-Common terminals.

Astable operation is enabled by a high level on the STABLE input or a low level on the ASTABLE\ input, or both. The period of the square wave at the Q and Q\ Outputs in this mode of operation is a function of the external components employed. "True" input pulses on the ASTABLE input or "Complement" pulses on the ASTABLE\ input allow the circuit to be used as a gateable multivibrator. The OSCILLATOR output period will be half of the Q terminal output in the astable mode. However, a 50% duty cycle is not guaranteed at this output.

The CD4047 triggers in the monostable mode when a positive-going edge occurs on the +TRIGGER-input while the -TRIGGER is held low. Input pulses may be of any duration relative to the output pulse.

The CD4047-Series types are supplied in 14-lead hermetic dual-in-line ceramic packages (F3A suffix), 14-lead dual-in-line plastic packages (E suffix), 14-lead small-outline packages (M, MT, M96, and NSR suffixes), and 14-lead thin shrink small-outline packages (PW and PWR suffixes).

1.What is the function of CD4047 ?

  • The CD4047 is a high-voltage multivibrator integrated circuit that can operate in both monostable and astable modes. To set the width of the output pulse in monostable mode and the frequency of the output pulse in astable mode, the IC requires an external resistor and capacitor.

2.What is a monostable multivibrator used for?

  • The monostable multivibrator is used in timing and delay circuits. It is responsible for the generation of clock pulses. It is used for ​the regeneration of distorted waves. It is also used in analogue systems to control the frequency of an output signal.

3.Why is multivibrator important?

  • A multivibrator circuit is nothing more than a switching circuit. It generates non-sinusoidal waves such as square waves, rectangle waves, and saw tooth waves, among others. Multivibrators are used as frequency generators, frequency dividers, and time delay generators, as well as memory elements in computers, and so on.
