UK Deliveries If you live on the UK mainland and don’t have any large materials or lithium batteries dwtasheet your order it will cost 3. These charges are usually billed to you directly from UPS. The outputs will change at one tenth the speed of the first B IC.

You’ve verified that LED 0 is connected to pin 3, dxtasheet to 2, 2 to 4, etc. Typical output drive at 5V: Further Information For information about all of the delivery options we offer click here.

Didn’t think about that. Max clock frequency at 5V: Delivery times vary for international orders depending on the service selected and the destination.

Do you have the datasheet for your specific ? Alternatively you can choose the free collection option and have your own courier collect it from us. Would you like to answer one of these unanswered questions instead? They can be used in timing circuits and are often used to datsheet on and off LEDs or motors or other circuits.

Collection If you would like dataseet collect your order, or use your own courier then there is an option you can select during checkout. They are versatile and relatively simple to put together. Supplying no voltage requires either a high-impedance output or leaving an input pin floating. A 16 DIL pin Decade Counter with 10 decoded outputs and inputs including, clock, reset, and clock inhibit.

The B Decade Counter

International orders may be charged import duty dependant on local import laws and duty rates. Rest of the world These orders are sent via UPS, and the cost is dependant on the service you choose at daasheet. A astable circuit is used to pulse the B at regular intervals. It has 16 pins and looks like any other 16 pin integrated circuit. That’s equivalent to 1. If the goods are not in stock we will endeavour to contact you as soon as possible to discuss a dispatch date.

Decade counter (4017B)

Drawing shows a pushbutton between Vcc and the actual power supply that is not on the schematic. Decade counter B How do you rate this product? Per Curd’s comment, I am also including the source current diagram from the datasheet.

If you spend over For a list of postcodes that will be charged the remote location rate click here. Thanks for the heads up! IgnacioVazquez-Abrams I didn’t know that. Counters such as the B are cheap and yet surprisingly useful.

The LEDs won’t be as bright, but it might be within your ‘s current sinking ability and at least allow you to determine if things are working correctly. I’m attempting to make a circuit that flashes each LED sequentially.



The B is most useful when combined with a timer such as a based circuit. Product Description The decade counter has ten output lines, one to represent each of the numbers 0 to 9, there is also a carry out line which goes high as the counter goes from 9 back round to 0.

This is essentially what I’m trying to create: The pulse from the IC is generated from pin 3.

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. Because it has attracted low-quality or spam answers that had to datahseet removed, posting an answer now requires 10 reputation on this site the association bonus does not count.

If that works, and you want datashdet make them brighter, you’ll need to either find a that has greater current ratings on the output pins or add some transistors. You can see the delivery time and cost at the shipping stage, or by using the shipping estimator from within the shipping basket.
