DATASHEET 4017B PDF
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. DESCRIPTION. The HCFB is a monolithic integrated circuit fabricated in Metal Oxide Semiconductor technology available in DIP and SOP packages.

I’m a first year student of E.
Curd You are correct, I had not paid attention to the schematic properly. The decade counter has ten output datasueet, 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.

That’s equivalent to 1. You’ve verified that LED 0 is connected to pin 3, 1 to 2, 2 to 4, etc. For the split second that it stops supplying voltage all the LEDs dimly flash on.

There are no product questions yet. Decade counter B How do you rate this product? You can figure out the resistor value to use by rearranging Ohm’s law: Note that the circuit you linked has a “1K2” resistor connecting the LEDs to ground negative.
A good example is seen below. Also note that the timer never actually “stops” supplying voltage; datasheer supplies a high voltage, and then it supplies a low voltage, repeatedly.

I’ll give it a go and see what happens. Typical output drive at 5V: Thanks for the heads up!
I’m attempting to make a circuit that flashes each LED sequentially. It is quite possible that you need more current than the can handle.

Thank you for your interest in this question. Add to Cart Details. As long as the clock inhibit is held low, upon a rising edge of the clock pin dtaasheet output will count up from zero, one number at a time for each rising edge on the clock pin. Per Curd’s comment, I am also including the source current diagram from the datasheet.
Do you have the datasheet for your specific ? 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.
Drawing shows a pushbutton between Vcc and the actual power supply that datzsheet not on the schematic. That picture isn’t exactly what I did but close enough that I thought it would help show what I was attempting. Email to a Friend.
Alternatively you can adtasheet the free collection option and have your own courier collect it from us. A astable circuit is used to pulse the B at regular intervals.

Didn’t think about that. In this circuit a reset switch has been added. These charges are usually billed to you directly from UPS. Continuous pulsing by the IC results the LEDs of the B turning on and off in sequence, creating a ripple effect. The LEDs won’t be as bright, but it might datasjeet within your ‘s current sinking ability and at least allow you to determine if things are working correctly.
