2024年12月10日 · A 4060 and a 4017 is a 4060 and a 4017, regardless of whether the prefix is CD or MC1 or HCF or HEF. They are just the prefixes of different manufacturers. To get accurate timing you should use the crystal timing circuit instead of the R/C version, although to get a 1Hz output pulse with a 32768 Hz watch crystal you will need to add an extra ...

2024年4月28日 · Single 4017 with each output connected to two resistors each connected to two LED anodes but their cathodes connected to two different transistor collectors. A single rising edge flip flop to drive into the base (via a resistor) of one or other of the transistors.

The way the 4017 counter works is that it turns the next output on for each clock cycle. For example, if output 0 is on, on the next clock cycle, output 0 will be off and output 1 will be on instead. My question is : is there another IC that does …

2017年6月28日 · Good day. I have a question in regards to the 4017 counter ic. I understand the reset pin needs to be low for counting to proceed and high to reset, however I have a circuit in mind that I would like to do that uses the 4017 to process short pulses. I need it to be reset for each pulse and the outputs will vary from pulse to pulse.

2014年10月27日 · I'm unsure of the inputs to the 4017 symbol. I've gone to the Yahoo group to get the CD4000_v.lib file, the CD4000 symbols folder and the instructions, and I have successfully added the symbol and model to my project. But the I don't get what those 3 inputs are. I need Reset, Clock and Enable.

2020年12月13日 · The emitter should connect directly to ground. A high on the 4017 output will then connect the LED cathode to ground. Each LED (or LED series string) needs a current limiting resistor. They cannot be connected to the transistor without one. Usually there is a base resistor connected to the 4017 output. However, the 4017 cannot source much current.

2010年3月16日 · With a 4017 Johnson counter, one output is always high, the rest are always low. When power is first applied, the counter may be in a random state; any one of the outputs may be high. If you want to make certain that they are all off when you power it up, connect an 0.1uF capacitor from the RESET input (pin 15) to Vdd (+V).
