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 outputs will change at one tenth the speed of the first B IC.

The 4107b 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. We have another pin called the carry out pin 12 th pinthis pin will stay low 0V by default.

The B Decade Counter

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. 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.

Connected to the Ground of the circuit.

Decade counter (B)

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 Be the first to review this product. Decade counter B How do you rate this product? This IC will increment the count from 0 to 9 Q0 to Q9 each time it senses a high pulse from the clock pin pin Click ask a question to be the first.


A 16 DIL pin Decade Counter with 10 decoded outputs and inputs including, clock, reset, and clock inhibit. Similarly, if the reset pin is made high. A good example is seen below. Output pins Q0 to Q9. They can be used in timing circuits and are often used to switch on and off LEDs or motors or other circuits. The pulse from the IC is generated from pin 3.

This is an input which when made high will hold the count at the current datashee. JavaScript seems to be disabled in your browser. If you spend over Complete Technical Details can be found at the CD datasheet given at the end of this page.

Add a timer to pulse the decade counter.

These are the 10 output pins on which the counting occurs, they are not in order hence verify pin diagram above. Write Your Own Review You’re reviewing: The B is an integrated circuit which has been designed to count pulses. For a list of postcodes that will be charged the remote location rate click datasheer.

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. The pulse from the timer can be used to activate the B circuit. TL — Programmable Reference Voltage. Add to Cart Details.


Same Day Dispatch Orders placed online before 3: The IC CD datasjeet 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.

Continuous pulsing by the IC results the LEDs of the B turning on and off in sequence, creating a ripple effect. If the goods are not in stock we will endeavour to contact you as soon as possible to discuss a dispatch date.

This pin goes high after the IC counts from 1 to It has 16 pins and looks like any other 16 pin integrated circuit.

International orders may be charged import duty dependant on local import laws and duty rates.


The timing diagram of the IC indicating the state of Output pins and Carry pin for every high pulse signal is shown below. Max quiescent datadheet at 5V: We do not charge a packaging or handling fee dattasheet 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.

Max clock frequency at 5V: If you spend between 40 and 48 – Sign up to our newsletter for promotions.

As the name suggests this pin resets the count back to 1. Counters such as the B are cheap and yet surprisingly useful.
