Does anyone know what I did wrong? You do have a resistor in series with the LED? Datashete think you are talking about the 0,1uF capacitor which should be connected to pin 5 control?

Smonjirez New Member Oct 9, Forums New posts Search forums. If you don’t then the circuit probably will not work properly. I’m currently working on a knight rider scanner.
How much current are adtasheet trying to draw from the pin? Well I haven’t ground pin 11 indeed. The problem is, I’ve got the timer to work, no problem there, can hcf017 the pulsing speed with a k potentiometer just mounted a LED to pin 3 with a ohm resistorno problems there.
The circuit will work alright if you cascade the counters. Articles Top Articles Search resources. The datasheet for the Cmos Intersil’s ICM shows that an ordinary causes a supply current spike of mA when its output switches.

Electro Tech is an online community with overmembers who enjoy talking about and building electronic circuits, projects and gadgets. Smonjirez New Member Oct 8, datasheeg Boncuk New Member Oct 6, This stays the same when I mount more LEDs to the other ports, it’s not how it’s supposed to be.
Smonjirez New Member Oct 6, The control pin has nothing to do with decoupling. Your CD is not connected to 0V so it cannot do anything. Boncuk New Member Oct ncf4017, Replacement Transformer Started by ncag Today at 7: Attached is a proper decoupling circuitry for the NE Plus, I don’t see any problems with how my chip functions, that one just works fine imo. Replacing a 4 pin leaded inductor with a 2 pin Started by gkmaia Yesterday at Else I still have no idea what to do.

The datasheet for National’s ordinary the LM shows that it needs two supply bypass capacitors to keep other ICs from crashing when the output switches. Did you try to sequence two? Why don’t people read the datasheets?? Got part of the scheme from internet Knight Rider lights for model cars and extended it myself with another additional chip to use 8 LEDs in this “back and forth” configuration.
According to the datasheets I followed it isn’t nessecary to connect pin 5. I don’t see the important supply bypass capacitors. To participate you need to register.
