And the biggie – capacitor leakage current. Oct 25, 4.

CD4060B Datasheet PDF

H CDB consists of an oscillator. Aug 1, 7, 2, Is this true since I so many schematics exceeding the 1Mohms. The 20 pin end lead shoulder width is a vendor option, either half or full width. All linear dimensions are in inches millimeters. Oct 25, 24 0. Since I already had the components for the available, I decided to build it on a protoboard. Data catasheet acquired from Harris Semiconductor.

I’ve never seen or heard of success at or above 10 M. Jun 8, 1, For example, the datasheet extract above indicates a max timing resistor of 20 M. TI is not responsible or liable for. GopherT do you mean pin 14 rather than pin 4?

That is an extremely high resistor value, and is based on the input stage device physics. Aug 23, 6, Oct 25, 7.


Information published by TI regarding third-party products or services. Pausing a counter based on a direct connection to its own output is a logic bomb, because there is no way to unpause it without overriding the output.

It does not account for any leakage current around the input pin due to dust and finger oil and other contaminants on the chip and the pc board, and it makes for a very high circuit impedance that is more susceptible to external noise.

Texas Instruments Incorporated and its subsidiaries TI reserve the right to make corrections, modifications. For your application, what is the mechanism external signal? Following are URLs where you can obtain information on other Texas Instruments products and application.

Oct 25, By the way, I hope all understand that though power supply decoupling capacitors are not shown on any of the schematics thus far, they should be present in the physical circuit. And to a previous point, not only is much innergoogle information unreliable, some of it is technically correct but incomplete without some experiencee or guidance.

Posted by PauloConstantino in forum: Schmitt trigger action on the. So 1 M is a common practical upper limit for the timing resistor, maybe more under controlled conditions. The oscillator configuration allows. If this is a problem, and you’re not married to theconsider the CD Believe everything you read.


Did you connect the anode to Q8 and the cathode to the Reset input, then add a k resistor from reset to ground so that the ‘ doesn’t stay in reset all the time? I did try to connect a diode from Q8 to pin 11, but it did not work as expected. Max Cx and Rx is supply voltage dependent but darasheet on the TI datasheet.

Your name or email address: Testing and other quality control techniques are used to the extent TI. Customers are responsible for. The resistor can vary over a wide range. This is a 24 stage counter with the last 8 bits brought out. ScottWang The op wants a 1 minute 60 second output.

Oct 25, 2. A high level on the. Post Office Box Dallas, Texas Mar 30, 7, 1, I need to obtain a periodic time of 60 seconds for the first pin Q3.

How can I ‘pause’ the circuit when a particular output is reached?

Oct 25, 5. Oct 2, 5, 1, RESET line accomplishes the reset function.

Do you already have an account? Resale of TI products or services with statements different from or beyond the parameters stated by TI for that. The CDB-series types are supplied in.
