The CD4047 is a versatile integrated circuit used in electronic mosquito repellers to generate a square wave signal, typically in the ultrasonic frequency range that mosquitoes find repellent. In the circuit, the CD4047 can be configured as an astable multivibrator, producing continuous oscillations. These oscillations drive a speaker or piezoelectric transducer, emitting sound waves that deter mosquitoes while being inaudible to humans. The frequency can often be adjusted to optimize its effectiveness against specific mosquito species.

Which IC you can use in place of cd4047?
You can use the CD4017 decade counter as a substitute for the CD4047 in certain applications, particularly for generating clock pulses or timing applications, as both are used in astable and monostable configurations. However, it's important to note that the CD4017 is primarily a counter and may not directly replicate all features of the CD4047, such as its dual operation modes. Always check the specific requirements of your circuit to ensure compatibility. Other alternatives could include the NE555 timer IC, depending on the intended application.
