Click ask a question to be the first. They are versatile and relatively simple to put together.

The timing diagram of the IC indicating the state of Output pins and Carry pin for every high pulse signal is shown below. You can see the delivery time and cost at the shipping stage, or by using the shipping estimator from within the shipping basket. Linking the B ICs together in this way allows for long interval timers to be made. Add to Cart Details.

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. They can be used in timing circuits and are often used to switch on and off LEDs or motors or other circuits. It also has the capability to indicate the status of counting using Carry pin.

The B Decade Counter

We have another pin called the carry out pin 12 th pinthis pin will stay low 0V by default. The B is an integrated circuit which has been designed to count pulses. There are no product questions yet. UK Deliveries Datassheet you live on the UK mainland and don’t have any large materials or lithium batteries in your order it will cost 3. Submitted by admin on 16 October The counting happens when this clock pulse goes highthis pin is normally connected to timer or other uC to produce a pulse.


The IC can provide up to The count will reset itself back to Q0 and will stay there until Q0 is made low again. Output pins Q0 to Q9. 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.

Continuous pulsing by the IC results the LEDs of the B turning on and off in sequence, creating daasheet ripple effect. Decade counter B How do you rate this product?

International orders may be charged import duty dependant on local import laws and duty rates. Max datasheeet frequency at 5V: Product Description The decade counter has ten output lines, one to represent each of the numbers 0 to datsheet, there is also a carry out line which goes high as the counter goes 4017v 9 back round to 0.

Decade counter (B)

This is an input which when made high will hold the count at the current state. Connected to the Ground of the circuit. 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.

A astable circuit is used to pulse the B at regular intervals. Be the first to review this product. This is commonly used for Led chasers and other logical output projects, so if you are looking for an sequential decoded counting IC that can count up to 10 then this IC will be your right choice.

Decade counter (4017B)

These are the 10 output pins on which the counting occurs, they are not in order hence verify pin diagram above. They are the Clock Enable pin 13 and Reset pin 15 pins.

A good example is seen below. If you spend over Collection If you would like to collect your order, or use your own courier then there is an option you can select during checkout. Rest of the world These orders are sent via UPS, and the cost is dependant on the service you choose at checkout.
