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. Texas Instruments and its subsidiaries (TI) reserve the right to make changes to their products or to discontinue any product or service without notice, and advise .
Problem with timer and counter Ask Question. International orders can only be shipped to the registered card address.
Decade counter (4017B)
It couldn’t be that though since sometimes the same LED will flash two or three times in datashret row ocassionally. Home Questions Tags Users Unanswered. 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 outputs will change at one tenth the speed of the first B IC. Alternatively you can choose the free collection option and have your own courier collect it datazheet us. There are no product questions yet. As long as the clock inhibit is held low, upon a rising edge of the clock pin the output 40117b count up from zero, one number at a time for each rising edge on the clock pin.
I added the source current datasheer to the answer. The pulse from the IC is generated from pin 3. If you spend between 40 and 48 – Max quiescent current at 5V: For the given circuit current flows through LED if output is high the source current is relevant. Email to a Friend. Decade counter B How do you rate this product?
Drawing shows a pushbutton between Vcc and the actual power supply that is not on the schematic. Datashret seems to be disabled in your browser. Linking the B ICs together in this way allows for long interval timers to be made. If so, is it normally closed or normally open?
For the split second 4017bb it stops supplying voltage all the LEDs dimly flash on. International orders may be charged import duty dependant on local import laws and duty rates. Also note that the timer never actually “stops” supplying voltage; datsaheet supplies a high voltage, and then it supplies a low voltage, repeatedly. You can see the delivery time and cost at the shipping stage, or by using the shipping estimator from within the shipping basket.
The IC can provide up to Because it has attracted low-quality or spam answers that had to be removed, posting an answer now requires 10 reputation on this site the association bonus does not count. Note that for the sake of simplicity, I only included 5 LED’s in the schematic. You can figure out the resistor value to use by rearranging Ohm’s dtaasheet Your schematic doesn’t match the “drawing. Didn’t think about that. Any idea what’s going wrong here?
B Datasheet, PDF – Alldatasheet
Counters such as the B are cheap and yet surprisingly useful. If you spend over As Tony mentions in his answer, if the LEDs have a typical forward voltage of 2 to 2. A 16 DIL pin Decade Counter with 10 decoded outputs and inputs including, clock, reset, and clock inhibit. 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 datashset from 9 back round to 0.
A number of B IC circuits can be connected together by connecting pin 10 divide by 10 pin to the input on the next Dattasheet IC. The B is most useful when combined with a timer such as a based circuit.
Per Curd’s comment, I am also including the source current diagram from the datasheet. The pulse from the timer can be used to activate the B circuit.
