The B is most useful when combined with a timer such as a based circuit. These charges are usually billed to you directly from UPS.

The IC CD is used for counting applications, it has the capability to turn on 10 outputs sequentially in a pre-defined time and reset the count or hold it when required. As the name suggests this pin resets the count back to 1. You can see the delivery time and cost at the shipping stage, or by using the shipping estimator from within the shipping basket.

Write Your Own Review You’re reviewing: TL — Programmable Reference Voltage. Product Description The decade counter has ten output lines, one to represent each of the numbers 0 to 9, there is also a carry 0417b line which goes high as the counter goes from 9 back round to 0.

This pin goes datashete after the IC counts from 1 to If you spend over It has 16 pins and looks like any other 16 pin integrated circuit. Similarly, if the reset pin is made high. Click ask a question to be the first. Complete Technical Details can be found at the CD datasheet given at the end of this page. Max quiescent current at 5V: A good example is seen below. This is an input which when made high will hold the count at the current state. We have 10 output pins ranging from Q0 to Q9, these pins can be connected to any load but we are using LEDs here as shown in the circuit below.


The pulse from the timer can be used to activate the B circuit. We do not charge a packaging or handling fee for this service, and you will receive an email when your order has been processed, you can collect half an hour after receipt of this email. They are the Clock Enable pin 13 and Reset pin 15 pins. International orders may be charged import duty dependant on local import datashete and duty rates.

But when the IC completes counting up to 10, the pin will go high and will remain high till it counts till 5, when its 5 it will go down 0V and turn on again when it reaches This is used as carry while counting.

They are versatile and relatively simple to put together. UK Deliveries If you live on the UK mainland and don’t have any large materials or lithium batteries in your order it will cost 3.

The timing diagram of the IC indicating the state of Output pins and Carry pin for every high pulse signal is shown below. These are the 10 output pins on which the counting occurs, they are not in order hence verify pin diagram above.


International orders can only be shipped to the registered card address. Add to Cart Details. The IC can provide up to The counter is reset to zero when the reset line is held in a high state. Add a timer to pulse the decade counter.

Typical output drive at 5V: If you spend between 40 and 48 – If the goods are not in stock we will endeavour to datasheef you as soon as possible to discuss a dispatch date.

The counting happens when this clock pulse goes highthis pin is normally connected to timer or other uC to produce a pulse.


The count will reset itself back to Q0 and will stay there until Q0 is made low again. Submitted by admin on 16 October In this circuit a reset switch has been added.

CMOS – CMOS – Decade counter with 10 decoded outputs

A astable circuit is used to pulse the B at regular intervals. Further Information For information about all of the delivery options we offer click here. The output changes sequentially from Q0 to Q9 for every high pulse from the Clock pin, but this sequence can be interrupted by two pins.

This ensures that they cannot be accidentally pulled off the circuit easily. A number of B IC circuits can be connected together by connecting pin 10 divide by 10 pin to the input on the next B IC. The decade counter has ten output lines, one to represent each of the numbers 0 to 9, there is also 4017 carry out line which goes high as the counter goes from 9 back round to 0.

Decade counter (4017B)

As long as the clock inhibit is held low, upon a rising edge of the clock pin the output will count up from zero, one datasjeet at a time for each rising edge on the clock pin. The wires from the battery snap and also the ones from the toggle switch are fed through small holes in the PCB. The B is an integrated circuit which has been designed to count pulses.

Decade counter B How do you rate this product? Output pins Q0 to Q9. JavaScript seems to be dtasheet in your browser. For a list of postcodes that will be charged the remote location rate click here.
