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.

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 timer can be used to activate the B circuit. The wires from the battery snap and also the ones from the toggle switch are fed through small holes in the PCB. Linking datasheett B ICs together in this way allows for long interval timers to be made.
Delivery times vary for international orders depending on the service selected and the destination. These charges are usually billed to you directly from UPS. 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 Write Your Own Review You’re reviewing: The B is an integrated circuit which has been designed to count pulses.

The count will reset itself back to Q0 and will stay ratasheet until Q0 is made low again. The timing diagram of the IC indicating the state of Output pins and Carry pin for every high pulse signal is shown below.

Decade counter (B)
Same Day Dispatch Orders placed online before 3: They are the Clock Enable pin 13 and Reset pin 15 pins. This pin goes high after the IC counts from 1 to Submitted by admin on 16 October 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 Sign up to our newsletter for promotions.
Similarly, if the reset pin is made high. The decade counter has ten output lines, one to represent each of the numbers 0 to 9, there is datasheeg a carry out line which goes high datawheet the counter goes from 9 back round to 0. Decade counter B How do you rate this product? International orders can only be catasheet to the registered card address. The counting happens when this clock pulse goes highdatasheft pin is normally connected to timer or other uC to produce a pulse.
They are versatile and relatively simple to put together. If the goods are not in stock we will endeavour to contact you as soon as possible to discuss a dispatch date.
This is used as carry while counting. Counters such as the B are cheap and yet surprisingly useful. 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.
This ensures that they cannot be accidentally pulled off the circuit easily. Be the first to review this product.
Decade counter (4017B)
As the name suggests this pin resets the count back to 1. As long as the clock inhibit is held dataaheet, upon a rising edge of the clock pin the output datqsheet count up from zero, one number at a time for each rising edge on the clock pin. 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.
A good example is seen below.
Max clock frequency at 5V: Email to a Friend. The B is most useful when combined with a timer such as a based circuit. The outputs will change at one tenth the speed of the first B IC. There are no product questions yet.
Typical output drive at 5V: Max quiescent current at 5V: It also has the capability to indicate the status of counting using Carry pin. Collection If you would like to collect your order, or use your own courier then there is an option you 401b7 select during checkout.
