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.

Delivery times vary dxtasheet international orders depending on the service selected and the destination. The count will reset itself back to Q0 and will stay there until Q0 is made low again.

For a list of postcodes that will be charged the remote location rate click here. This is used as carry while counting. This is an input which when made high will hold the count at the current state.

These are the datashest 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. The pulse from the IC is generated from pin 3. If you spend between 40 and 48 – It also has the capability to indicate the status of counting using Carry pin.

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 number at a time for each rising edge on the clock pin. But when the IC completes counting up to 10, the pin will go high and will remain high till it counts till 5, when daasheet 5 it will go down 0V and turn on again when it reaches Click ask a question to be the first.


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. If you spend over 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. The output changes ratasheet from Q0 to Q9 for every high pulse datashee the Clock pin, but this sequence can be interrupted by two pins.

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.

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

Decade counter (B)

They are versatile and relatively simple to put together. This ensures that they cannot be accidentally pulled off the circuit easily. In this circuit a reset switch has been added.

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. 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 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 you live on the UK mainland and don’t have any large materials or lithium batteries in your order it will cost 3. A good example is seen below.

The B is most useful when combined with a timer such as a based circuit. The pulse from the timer can be used to activate the B circuit. Write Your Own Review You’re reviewing: Complete Technical Details can be found at the CD datasheet given at the end of this page.


Decade counter (4017B)

Counters such as the B are cheap and yet surprisingly useful. You must have JavaScript enabled in your browser to utilize the functionality of this website. International orders can only be shipped to the registered card address. International orders may be charged import duty dependant on local import laws and duty rates. As the name suggests this pin resets the count back to 1.

They can be used in timing circuits and are often used to switch on and off LEDs or motors or other circuits. They are the Clock Enable pin 13 and Reset pin 15 pins. These charges are usually billed to you directly from UPS. Collection If you would like to collect your order, or use your own courier then there is an option you can select during checkout.

Linking the B ICs together in this way allows for long interval timers to be made. The wires from the battery snap and also the ones from the toggle switch are fed through small holes in the PCB. TL — Programmable Reference Voltage. The counter is reset to zero when the reset line is held in a high state. Max clock frequency at 5V: If the goods are not in stock we will endeavour to contact you as soon as possible to discuss a dispatch date.
