For example suppose initially the pin is connected to the ground for enabling the Datasbeet to oscillate let say for 5 minute, connecting the pin to the positive would immediately halt the counting after 5 minutes and reset it back to zero.

CD Datasheet, PDF – Alldatasheet

Thus a particular value of resistor, for fixed voltage, limits the current through it. Datasheets, Manuals or Parts.

You must log in or register to reply here. Similarly if you have connected the rotary switch to pin 5, then at this time Q5 gives 32 divisions ce4060 it will give an alarm after 30 seconds and continue to give alarm until you switch off the alarm externally.

Hero Banned Apr 13, To solve this problem we have described a circuit below which gives an alarm after the preset time interval selected by you.


If not, a good source is old clocks and watches Can you get hold of a 4. Rest I can manage. Anyway, another reason to use a watch crystal is that Hz crystals tend to be daasheet stable and accurate than other crystals for the same price.

I’ve never seen a 3. If you use a Hz signal, with the CD, you’ll get a 2Hz time base which can be divided by 2, to get i using a single flip-flop. If not, a good source is old clocks and watches. A speaker is commonly used The other pin is connected to ground. When counter reaches bit Q4pin 7 goes high so that the buzzer connected with the relay with the transistor turn on.

Use a 74HC instead. datashet

The charge q stored in a capacitor is the product of its capacitance C value and the voltage V applied to it. Note that Q and Q11 are not available. Click here to register now.

Timer Circuit using IC CD 4060

Its resistance is given by the ratio of voltage applied across its terminals to the current passing through it. You should be able to buy a Hz crystal from most suppliers. Now we can connect other output also with the rotary switch to get different time period.

The timer circuit is built around the CD which is 14 stage ripple carry binary counter, divider and an oscillator. I do have plenty of old watches, but since I don’t see any label in the crystal, how can I be sure about its frequency? Datasbeet have heard somewhere that it cd40060 work!

Image cd4006 shows the pin layout of the IC: BC is an NPN bi-polar junction transistor. Its inbuilt oscillator is based on three inverters. Skip to main content.


Crystal oscillator using 4060

Alarm can be adjusted for duration of 30 seconds to 2 hour 30 minutes. Electro Tech is an online community with cimembers who enjoy talking about and building electronic circuits, projects and gadgets.

It is important to connect pin 12 reset pin to ground for enabling the IC to oscillate and we have connected it to cd40660 supply.

Hi, I want to make a crystal datasgeet using the IC cd Therefore after a preset interval of time it will give a datashest alarm and reminds you that you have to off your machine or gas. Failing that, what crystals can you get hold of? Capacitors offer infinite reactance to zero frequency so they are used for blocking DC components or bypassing the AC signals. Forums New posts Search forums.

Choosing Motor For Robots. You can test it with the following circuit which will give a 2Hz output, add another flip-flop to divide that by 2 and you have your 1Hz timebase.

The datasheet for the crystal will list the recommended capacitor values including stray capacitance. Hero Banned Apr 11, This happens because we have connected pin 11 through a diode, oscillation stop and IC remains latched in high state until it resets.
