DESCRIPTION. The HCFB is a monolithic integrated circuit fabricated in Metal Oxide Semiconductor technology available in DIP and SOP packages. IC is a CMOS counter/divider integrated circuit, actually a decada counter with 10 decode ouputs. It is 5 stage Johnson counters having 10 decoded.

The count will reset itself back to Q0 and will stay there until Q0 is made low again. 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. For a list of postcodes that will be charged the remote location datsaheet click here.

Complete Technical Details can be found at the CD datasheet given at the end of this page. The counter is reset to zero when the reset line is held in a high 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. Click ask a question to be the first. In this circuit a reset switch has been added. JavaScript seems to be disabled in your browser. Delivery times vary for international orders depending on the service selected and the destination. The pulse from the IC is generated from pin 3.

A good example is seen below. Similarly, if the reset pin is made high. The counting happens when this clock pulse goes highthis pin is normally connected to timer or other uC to produce a pulse.

Decade counter (4017B)

It also has the capability to indicate the status of counting using Carry pin. Linking the B ICs together in this way allows for long interval timers to be made. Collection If you would like to collect your order, or use your own courier then there is an option datashee can select during checkout.


This is an input which when made high will hold the count at the current state. 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.

CMOS – CMOS – Decade counter with 10 decoded outputs

International orders may be charged import duty dependant on local import laws and duty rates. They are versatile and relatively simple to put datashwet. The B is most useful when combined with a timer such as a based circuit. You can see the delivery time and cost at the shipping stage, or by using the shipping estimator from within the shipping basket. It has 16 pins and looks like any other 16 pin integrated circuit.

A 16 DIL pin Decade Counter with 10 decoded outputs and inputs including, clock, reset, and clock inhibit. International orders can only be shipped to the registered card address.

IC CD Pinout, Description, Equivalents & Datasheet

Connected to the Ground of the circuit. 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 This pin goes high after the IC counts from 1 datasheeet Max clock frequency at 5V: Submitted by admin on 16 October Email to a Friend.

Rest of the world These orders are sent via UPS, and the cost is dependant on the service you choose at checkout. We have another pin called the carry out pin 12 th pinthis pin will stay low 0V by default.

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. Counters such as the B are cheap and yet surprisingly useful. Decade counter B How do you rate this product?


A number of B IC circuits can datasheer connected together by connecting pin 10 divide by 10 pin to the input on the next B IC. The timing diagram of the IC indicating the state of Output pins and Carry pin for every high pulse signal is shown below. UK Deliveries If 4017g live on the UK mainland and don’t have any large materials or lithium batteries in your order it will cost 3.

This is used as carry while counting. But when the IC completes counting up to 10, the pin 4107b 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 Write Your Own Review You’re reviewing: These charges are usually billed to you directly from UPS.

This ensures that they cannot be accidentally pulled off the circuit easily. These are the 10 output pins on which the counting occurs, they are not in order hence verify pin diagram above.

Continuous pulsing by the IC results the LEDs of the B turning on and off in sequence, creating a ripple effect. Max quiescent current at 5V: Add a timer to pulse the decade counter.

A astable circuit is used to pulse the B at regular intervals. If you spend over If the goods are not in stock we will endeavour to contact you as soon as possible dwtasheet discuss a dispatch date.
