IC 4047

16

The IC 4047 is one of those devices which promises an unlimited range of circuit application solutions. The IC is so versatile that on many occasions it easily outsmarts it's close rival, the IC 555, let's study the datasheet and pinout details of this versatile chip.

  • In-built oscillator with variable frequency option through an external RC network.
  • Complementary push-pull outputs with a separate active clock output, the clock output is actually an extension of the internal oscillator frequency output.
  • Duty cycle locked to 50% for precision, fail proof operation of the external stages.
  • The IC 4047 can be configured as a free running astable MV, and also as a monostable MV.

The IC 4047 is one of those devices which promises an unlimited range of circuit application solutions. The IC is so versatile that on many occasions it easily outsmarts it's close rival, the IC 555, let's study the datasheet and pinout details of this versatile chip.


Main Datasheet and Specifications of the IC 4047:

In-built oscillator with variable frequency option through an external RC network.

Complementary push-pull outputs with a separate active clock output, the clock output is actually an extension of the internal oscillator frequency output.

Duty cycle locked to 50% for precision, fail proof operation of the external stages.

The IC 4047 can be configured as a free running astable MV, and also as a monostable MV.

In the astable mode the chip provides the option of integrating external triggering inputs, also called true gating and compliment gating modes.

The monostable mode enables positive edge triggering as well as negative edge triggering of the IC. It further alows retriggerable feature for extending the output timing to the desired calculated level. Meaning after the normal trigger is applied to the IC, more number subsequent triggers can be applied so that the output adds up the timing, generating further delay at the output.

The following explanation suggests how the pinouts of the IC 4047 may be configured for implementing the above discussed operating modes:

 In the free running astable mode, connect pins 4, 5, 6, 14 to positive or Vdd, connect pins 7, 8, 9, 12 to ground or Vss.

In gated astable mode connect pins 4, 6, 14 to positive or Vdd, connect pins 7, 8, 9, 12 to ground or Vss, connect pin 5 to the reset pin of the external trigger IC, while output of the external chip to pin 4 of the IC 4047.

For the above modes, the output may be obtained across pin 10, 11 (push-pull) while clocks at pin 13.

In positive trigger monostable mode, connect pins 4, 14 to positive or Vdd, connect pins 5, 6, 7, 9, 12 to ground or Vss, connect pin 8 to the reset pin of the external trigger IC, while output of the external chip to pin 6 of the IC 4047.

For the above modes, the output may be obtained across pin 10, 11.

The IC 4047 is one of those devices which promises an unlimited range of circuit application solutions. The IC is so versatile that on many occasions it easily outsmarts it's close rival, the IC 555, let's study the datasheet and pinout details of this versatile chip.
