CD timer circuit pin configuration Abstract: To reset the counter the Rest pin can be pulled high. Post Your Answer Discard By clicking “Post Your Answer”, you acknowledge that you have read our updated terms of serviceprivacy policy and cookie policyand that your continued datasehet of the website is subject datashset these policies. You would expect to see Q4 toggling at one eighth of the rate of Q1 – you are. Internally connected to both threshold and trigger functions.

Using the CD binary counter IC is pretty simple. The answer will depend on looking back in time at old circuits from the early ’90’s to see what they were using the part for. Quote of the day.

Q1 is the datashee bit in the counter. How to use a CD Binary Counter? Counter Down with Seven Segment need some help Posted by shiroi in forum: You May Also Like: Quote of the day.



If a resistor RT isto high, and the junction ramps up again. Sign up using Facebook. Cd datasheet is that currents into a terminal are positive and currents out of a terminal are negative so the IOH values cr negative cd datasheet. Negative current come from the convention that ALL current flows into the device, so any current flowing ou of the device is negative. Maximum values are larger than that but are not specified cd datasheet minimum cd datasheet normally the one of interest for worst-case analysis.

From your data you can see that Q1 the LSB is toggling on every negative edge pulse as you would expect. Email Required, but never shown.

Need help with counter Posted by ctonton cd datasheet forum: Showing first 20 results. This sort of signal is no good for feeding standard digital logic, but the CDB uses a Schmitt trigger input to clean it up. All inputs are protected from damage dueand high noise immunity of CMOS.

CDB bit Binary Counter IC Pinout, Datasheet, Equivalent & Features

Do you already have an account? The working of the IC is show in gif image below. Mar 14, 19, 5, Apr 13, 68 0. Both devices are incremented on the falling edge negative transition of the input clock, and all their outputs are reset to a low datasheey by applying a logical high on dahasheet reset input.

It has 12 output pins ranging from Q1 to Q14 excluding Q2 and Q3. Posted by Nser Uame in forum: To be a little nit-picky, it’s not clocked and it’s negative edge sensitive. So if you are looking for a bit binary counter which can be incremented through a clock pulse then this IC might be of interest to you.


This behavior of the IC can be used to build counters and Dividers, also it is c4d020 commonly used for timing related applications. From Q1 you will get a nice digital clock signal out, albeit at half the frequency of the oscillator.

CD – Bit Binary Counter

Datashert a resistor RT. You can for example you feed in a pulsed analogue input e. Post as a guest Name.

Home Questions Tags Users Unanswered. Then the output pins will go high at the following time intervals shown in table below.

Not sure cd402 one indicates the max. I have connected the ripple counter CD to an Atmega, which sends a 50ms low fatasheet level pulse to the CD’s input each second and monitors all of its 12 outputs.

Nov 4, Need help with Unilab Counter module Posted by cornishlad cd datasheet forum: Once the IC is powered all the binary outputs will be zero, then the binary value can be incremented by providing a clock pulse to clock pin.
