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.

Rest of the world These orders are sent via UPS, and the cost is dependant on the service you choose at checkout. Add to Cart Details. The B is an integrated circuit which has been designed to count pulses. JavaScript seems to be disabled in your browser.

TL — Programmable Reference Voltage. The counter is reset to zero when the reset line is held in a high state. Delivery times vary for international orders depending on the service selected and the destination. As the name suggests this pin resets the count back to 1. A 16 DIL pin Decade Counter with 10 decoded outputs and inputs including, clock, reset, and clock inhibit.

The Catasheet can provide up to Click ask a question to be the first.

Decade counter (4017B)

In this circuit a reset switch has been added. This is an input which when made high will hold the count at the current state.

Further Information For information about all of the delivery options we offer click here. There are no product questions yet. Continuous pulsing by the IC results the LEDs of the B turning on and off in sequence, creating a ripple effect.


Output pins Q0 to Q9. A good example is seen below. Max quiescent current at 5V: If you spend over These are the 10 output pins on which the counting occurs, they are not in order hence verify pin diagram above.

The pulse from the timer can be used to activate the B circuit. They are the Clock Enable pin 13 and Datassheet pin 15 pins. The B is most useful when combined with a timer such as a based circuit. Complete Technical Details can be found at the CD datasheet given at the end of this page. This is used as carry while counting.


International orders can only be shipped to the registered card address. The output changes sequentially datasbeet Q0 to Q9 for every high pulse from the Clock pin, but this sequence can be interrupted by two pins. Be the first to review this product. You can see the delivery time and cost at the shipping stage, or by using the shipping estimator from within the shipping basket.

CMOS – CMOS – Decade counter with 10 decoded outputs

The outputs will change at one tenth the speed of the first B IC. You must have JavaScript enabled in your browser to utilize the functionality of this website. Sign up to our newsletter for promotions. Linking the B ICs together in this datasheeh 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 you can select during checkout. Add a timer to pulse the decade counter. Connected to the Ground of the circuit. Submitted by admin on 16 October Datssheet counting happens when this clock pulse goes highthis pin is normally connected to timer or other uC to produce a pulse.


IC CD Pinout, Description, Equivalents & Datasheet

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 Email to a Friend.

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 401b7 hour after receipt of this email. The pulse from the IC is generated from pin 3. The decade counter has ten output lines, one to represent each of datashest numbers 0 to 9, there is also a carry out line which goes high as the counter goes from 9 back round to 0.

Same Day Dispatch Orders placed online before 3: The count will reset itself back to Q0 and will stay there until Q0 is made low again. 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.
