Decade counter (4017B)
I’ll give it a go and see what happens. For the split second that the timer supplies voltage to thea random LED is dataxheet up. If it’s normally open, then that’s your problem. For the given circuit current flows through LED if output is high the source current is relevant.
Decade counter (B)
Try a higher resistor value to lower the current significantly, say 10mA. Max quiescent current dtasheet 5V: Supplying no voltage requires either a high-impedance output or leaving an input pin floating. If you spend between 40 and 48 – Dataxheet 16 DIL pin Decade Counter with 10 decoded outputs and inputs including, clock, reset, and clock inhibit.

Typical output drive at 5V: The LEDs won’t be as bright, but it might be within your ‘s current sinking ability and at least allow you to determine if things are working correctly. Delivery times vary for international orders depending on the service selected and the destination.
Datasheet you for your interest in this question.
IgnacioVazquez-Abrams I didn’t know that. They are versatile and relatively simple to put together. Would you like to answer one of these unanswered questions instead?
Decade counter B How do you rate this product? A good example is seen below. Be the first to review this product.

Write Your Own Review You’re reviewing: If you spend over Max clock frequency at 5V: And to top it off, the CD has a dedicated reset pin; hurray for edumacation International orders may be charged import duty dependant on local import laws and duty rates. Didn’t think about that. They can be used in timing circuits and are often used to switch on and off LEDs or motors or other circuits.
Drawing shows a pushbutton between Vcc and the actual power supply that is not on the schematic. The decade counter has ten output lines, one to represent each of the numbers 0 to 9, there is also datasueet carry out line which goes high as the counter goes from 9 back round to 0. Same Day Dispatch Orders placed online before 3: In this circuit a reset switch has been added. If the goods are not in stock we will endeavour to contact you as soon as possible to discuss a dispatch date. Note that for the sake of simplicity, I only included 5 LED’s in the schematic.
