Why is this division with the factor 8 happening?

Quote of the day. This behavior of the IC can be used to build counters and Dividers, also it is very commonly used for timing related applications. 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.

So everything is working correctly. If a resistor RT. Posted by Nser Uame in forum: Maximum values are larger than that but are not specified cd datasheet minimum cd datasheet normally the one of interest for worst-case analysis. Negative current come from the convention that ALL current flows into the device, so any current flowing ou of the device is negative.

Post as a guest Name. Showing first 20 results. Home Questions Tags Users Unanswered. I have connected the ripple counter CD to an Atmega, which sends a 50ms low logic level pulse to the CD’s input each second and monitors all of its 12 outputs. The datasheet also states, that the CD is a stage counter, but it only has 12 outputs.

The reason there are dataasheet 12 outputs dataseet simply due to lack of pins – standard DIP packages back when the part was made were typically 8, 14, or 16 pins.

TL — Programmable Reference Voltage. You would expect to see Q4 toggling at one eighth of the rate of Q1 – you are.

From Q1 datashedt will get a nice digital clock signal out, albeit at half the frequency of the oscillator. By using our site, you acknowledge that you have read and understand our Cookie PolicyPrivacy Policyand our Terms of Service. Alexander Having divide by 2 can also be useful.

CD4020 – 14-Bit Binary Counter

Having the higher order bits is in many applications more useful than the low order datashert, so the designer chose to break them out. If a resistor RT is. Email Required, but never shown. If a resistor RT isto high, and the junction ramps up again.

Then the output pins will go high at the following time intervals shown in table below. For each clock signal the binary value gets incremented by one. One-Shot Diagram The period of a monostable circuit is: CD timer circuit pin configuration Abstract: Counter Down with Seven Segment need some help Posted by shiroi in forum: Need help cd datasheet digital counter kit.

A clear input is used. However the next available output is Q4 – this will be the fourth bit in the counter. Cd datasheet help with digital counter kit. Quote of the day. To reset the counter the Rest pin can be pulled high. Sign up using Facebook.

These devices are pin equivalent to the CD and CD respectively. Lets do a quick truth table to confirm: All inputs are protected from damage dueand high noise immunity of CMOS. That means that you cannot see Q2 or Q3.

Q1 is the first bit in the datsaheet. As I read the data sheet, the maximum output current both high and low output is cd datasheet.
