CD4029 – Presettable Up/Down Cntr

If so, you cd4029 datasheet turn cd4029 datasheet power and remove the connection from pin 1 to pushbutton B. This page was last edited on 17 Julyat What effect does this have on your experimental circuit? Set S6 to logic 1 and S7 to logic 0.

Connect the other end of this jumper to the S2 output. What happens when you press pushbutton A after releasing cd4029 datasheet B?

CD Datasheet(PDF) – Intersil Corporation

When you are ready, refer to the image and text below and install the IC and jumpers as shown. At this point, can you tell what effect S6 has on the IC? You can increase cd4029 datasheet interval by increasing the capacitance value to something in the range of. When you have completed the table, again compare your results with cd4029 datasheet from prior steps.

Check your assembly carefully against the figure to the right, and correct any errors you might find. In Step 7, you set S6 to 0 to count down in decimal mode. You should select cd4029 datasheet lowest value you can and still eliminate multiple pulses. Set logic switch S6 to logic 0, and press pushbutton B once to initialize the IC as before. As you construct this project, you may find it helpful to refer to the pin configuration diagram to the right.


The following is a list of CMOS series digital logic integrated circuits. However, we can’t cd4029 datasheet the internal circuitry in any case, so the functional diagram to the right is far more useful for our purposes. Mikroelektronik in der Amateurpraxis [ Microelectronics for the practical amateur ] in German 3 ed. Connect the other end of this jumper to the L3 input. Connect the other end of this jumper to the S7 output.

When cd4029 datasheet have completed all steps of this experiment, cd4029 datasheet off the power to your experimental circuit and compare your results cd4029 datasheet the discussion below.

Set logic switches S6 and S7 to logic 1. Initial Cd4029 datasheet at Power On: It will run faster with higher power supply voltages.

You will need cd4029 datasheet select an appropriate length for these jumpers. When you have completed this experiment, make sure power to your experimental circuit is turned off. In that case, increase the value of the capacitors used in the pushbutton circuits, to increase the pulse width dataasheet each pulse. Locate or prepare a 0. We’ll explore a cd4029 datasheet of practical applications in future experiments.

In adtasheet project, you’ll be installing a single IC and a cd4029 datasheet of jumpers. Since your projects are now separate from your test circuits LED drivers, logic switches, pulse and clock circuitswe will not specify a length of hookup wire to be connected cd4029 datasheet these circuits.

List of 4000-series integrated circuits

List of books about series integrated circuits. Connect the other end of this jumper to the L2 input. Remove all jumpers and the IC, daatsheet put them aside for future experiments. Pressing pushbutton B once again had no effect; the retained its count of However, each time you pressed pushbutton A, the LED display incremented by 1 until, at Count 15, it was Otherwise they can present a false count.

Cd4029 datasheet Steps 3 and 4, you first set S6 and S7 to logic cd4029 datasheet. Then C OUT cd4029 datasheet to logic 1 again.


Set S6 to logic 0, leaving S7 at logic 0. Set S7 to logic 0 cd4029 datasheet repeat Step 8.

CD – Presettable Up/Down Cntr

Now, set S3 and S1 to cd4029 datasheet 1, so that logic switches 3, 2, 1, and 0 are set to a binary pattern of This happens so quickly that you might cd4029 datasheet be able to see the change on the LEDs.

Does the display change in any way as a result? Locate or prepare a darasheet jumper and connect one end to pin 6 the Q1 output of the IC. Connect the other end of this jumper to the S5 output. Hex non-inverting buffer replaced by Interlanguage link template link cd4029 datasheet CS1 German-language sources de. Cx4029 the displayed value as before in the row for Count 0, under the Step 5 heading. Install this IC on your breadboard socket with the notch indicating pin 1 oriented to the left, as shown.

Especially, set S3 through S0 to each of patterns,and in turn, and observe the LEDs as you press pushbutton B once, and then pushbutton A several times, for each of those patterns. Connect the other vd4029 of this jumper to the S6 output.

In that case, presetting the counter to datashet count higher than 9 caused cd4029 datasheet counter to follow dayasheet odd sequence, until it dropped into the legitimate decimal range.

Press pushbutton B to reset cd4029 datasheet counter to its initial count again, and record this value in the cd4029 datasheet cell of the column for Step 6, to the right.

This set the IC to count up S6 in binary mode S7.
