Find out how easy it is to wire a IC with just a hand full of components and obtain multiple frequency outputs. The oscillator is popularly used and this . CD is the versatile Binary counter IC that can be used in Timer applications. When a resistor is connected to its pin 10 and a capacitor in. Another versatile device, the IC has numerous applications and can be used for implementing various useful functions in an electronic.

Timer Circuit using IC CD 4060
Sorry, your blog cannot share posts by email. Interface SD Card with Arduino. Capacitors offer infinite reactance to zero frequency so they are used for blocking DC components or bypassing the AC signals.
Positive supply is given to pin A speaker is commonly used The other pin is connected to ground. Skip to main content.
IC 4060 Oscillator Explained
Pin 8 is to be connected to the ground. Resistor Resistor is a passive component used to control current in a circuit. The resistor at pin 10 or the capacitor can be made variable, if the frequency is to be varied, otherwise fixed values may be chosen.
Resistor at pin 11 should be roughly 10 times that of resistor at pin Its ten active high outputs can give time delay from few seconds to hours. Generally most Cdd4060 have a sunken circle just beside pin 1, otherwise it can be identified as follows:.
To get c4d060 time period, output Q11 is omitted in the IC itself so that double time is available between Q10 and Q Pin 12 is the reset pin.
When the high output is connected to the pin 11 clock iic through a diode, oscillation stops and IC remains latched in the high state till it resets. Generally most ICs have a sunken circle just beside pin 1, otherwise it can be identified as follows: The free ends of these components are all joined together. Here, IC1 works as frequency divider circuit.
Several cdd4060 we forget to switch off the gas, electric oven, stove or motor while watching TV or taking on the phone or while talking to a friend in your neighborhood. How IC is Wired as an Oscillator? If you want to get alarm after every preset time interval, then remove this diode.
Internally the oscillator signal is applied to the first bistable which drives the second bistable jc so on. The frequency of each output will be the double of the previous one and is obtained in serial order through pin 3, 2, 1, 15, 13, 14, 6, 4, 5, and 7.
Timer Circuit using IC CD
Heavy loads such as relay can be operated through a driver transistor. Its inbuilt oscillator is based on three Inverters. Its inbuilt oscillator is based on three oc. The oscillator can be latched after a set period by connecting the appropriate output to pin 11 through a diode. Each output goes high in the lc transition after the completion of one timing cycle. Outputs Q1-Q3 is also absent and the output starts from Q4. Here we have used a rotary switch to select the time required.
When counter reaches bit Q4pin 7 goes high so that the buzzer connected with the relay with the transistor turn on. The basic frequency of the internal oscillator is determined by the value of the capacitor connected to its pin 9 and the resistor connected to pin The oscillator can be stopped or reset by applying a logic 1 or a positive supply to pin 12 of the IC.
Ten of these fifteen signals are available on the output pins Q4- Q A transistor, stands for transfer of In this you can select 7 different time intervals with the help of a rotary switch. By continuing to use this website, you agree to their use.
Design Your Circuit. Part II – CD Timer – Mohan’s electronics blog
Alarm can be adjusted for duration of 30 seconds to 2 hour 30 minutes. Its 16 pins lc designated as follows: So that counter will start again. It is important to connect pin 12 reset pin to ground for enabling the IC to oscillate and we have connected it to positive supply. Virgin Galactic — Commercial Space Flight. To find out more, including cdd4060 to control cookies, see here: Image below shows the pin layout of the IC: The basic frequency cd406 the internal oscillator is determined by the value of the timing capacitor connected to its pin 9 and that of the timing resistor in its pin Reset pin 12 should be grounded.
The IC requires just a couple of resistors and a capacitor connected externally to start the oscillator. Reset pin 12 resets the timing cycle once it is grounded.
