Imagine a simple normally-open push button. The opinions expressed in those weblogs and hence this aggregation are those of the original authors. It is also available in surface mount, and other newer package styles.
This is the pin DIP package. Planet Arduino is, or at the moment is wishing to become, an aggregation of public weblogs from around the world written by people who develop, play, think on Arduino platform and his son.
As always, thank you for reading and I look forward to your comments and so on.
Four switches in one IC. We do not edit, endorse or vouch for the contents of individual posts. Practice makes perfect and all that.
Here is a diagram: And the ubiquitous video: First of all, here is a 7h4c4066 of the switches being turned on and off one at a time:. All these parameters and more are available from the data sheet pdf. Entries on this page are owned by their authors.

You press the button, and current can flow through the switch. 74hc40066 when you need a few of them, it can be easier to start using these 74HCs as long as the current requirements are met. I know these simple demonstrations may be… well a little simple, but after taking the time to build 7h4c4066 from scratch you get a better understanding of the part and how they work.
Our first demonstration is quite simple — just switch on and off some LEDs via a 74HC shift register and an Arduino. Furthermore, this would 74yc4066 apply if the current restrictions of the IC are met. Please subscribe using one of the methods at the top-right of this web page to receive updates on new posts.
Well that was interesting. Consider 74h4066 circuit below: This is where the benefit of the IC comes to mind, normally one might use a 1k ohm resistor and an NPN switching transistor as an electronic switch, and I have done so myself.
Just fill 7h4c4066 the information below and submit. Using the 74HC, when current is applied to the E pin, current can pass through from the matching Y pin to the Z pin.
Consider the circuit below:. Otherwise, have fun, be good to each other — and make something! First of all, here is a video of the switches being turned on and off one at a time: The 74HC switches creates a final voltage 74hc40066 the sum of various currents being switched into the final output. With regards to the current the IC can switch, Is, the maximum is 25mA per switch.
This was a good suggestion, however 74yc4066 can only switch a current of 10mA per pin.
As you can see above, there are four of these switches in the IC. My reason for writing this comes 74hc466 a comment left by a reader on chapter nine of the Arduino tutorial. Well I hope you found this part review interesting, and helped you think of something new to make. And here is the Arduino sketch:
