Timer Circuit using IC CD 4060

Here is a typical example of a chip that might be suitable for a 5V supply not a recommendation of this dayasheet Maxim part. Similarly if you have connected the rotary switch to pin 5, then at this time Q5 gives 32 divisions and it will give an alarm after 30 seconds and continue to give alarm until you switch off the alarm externally. Group all Htabs Electronics.

Show me me your Vcc on power up and your schematic and layout and I will tell you why it happens to you and how to prevent it with POR or other methods. My circuit with a BE IC has nothing else but a resistor and a capacitor, and it appears to start with all logic 0.

BE NTE Equivalent NTEB IC-CMOS DIVIDER & O – Wholesale Electronics

This happens because we have connected pin 11 through a diode, oscillation stop and IC remains latched in high state until it resets. Check this assumption and increase R2C2 while satisfying below datasheet requirements to fix your problem.

Choosing Motor For Robots. Several times 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.


Relay Switch Relay is an electromagnetic device which is used to isolate two circuits electrically and connect them magnetically. By increasing or decreasing the value of capacitor and resistor, we can change the time delay for the period of on and off.

Speaker A loudspeaker or “speaker” is a transducer that converts electrical energy into acoustical energy. I do recall having Pin 12 connected straight to ground, however I guess I must use a capacitor and resistor in series.

Note that Q and Q11 are not available. The other pin is connected to ground. Sign up or log in Sign up using Google. Home Questions Tags Users Unanswered. Thus a particular value of resistor, for fixed voltage, limits the current through it.

Tony EE rocketscientist Skip to main content. The timer circuit is built around the CD which is 14 stage ripple carry binary counter, divider and an oscillator. A transistor, stands for transfer of These are generically known as supervisory chips when supplied in monolithic form. 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 Post as a guest Name. To solve this problem we have described a circuit below which gives an alarm after the preset time interval selected by you.

A sufficiently large bypass capacitor, which you should have anyway, will prevent that in almost all situations. The only thing you need to do to make this absolutely bulletproof is to ensure that the supply cannot dip for an extremely short time such that the ms pulse would not be triggered but the counter would be corrupted. If you followed the rules in the datasheet. Its inbuilt oscillator is based on three inverters. Sign up using Facebook. Then the next clock edge is determined by R1C1 time constant so R2C2 determines the latency needed to let power up stabilize.


Resistor Resistor is a passive component used to control current in a circuit.

This is done so that it instantly stops the IC from oscillating and dataaheet it back to its original stage. If you want to get alarm after every preset time interval, then remove this diode. Capacitors offer infinite reactance to zero frequency so they are used for blocking DC components or bypassing the AC signals.

Surely as datasheeet a binary counter, its meant to start with all outputs on logic 0, and count up using binary? Now we can connect other output also with the rotary switch to get different time period. They are omnipresent in 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.

S1 connected to pin.

Image below shows the pin layout of the IC: Its resistance is given by the ratio of voltage applied across its terminals to the current passing through it. Here’s an example of resetting the chip with a resistor and a capacitor at power-on: Email Required, but never shown.

Interface GPS with Arduino. Thanks, I will check. Since each bistable divides its input signal by two, a total of fifteen signals are available, each of half the frequency of the previous one.
