First of all, here is a video of the switches being turned on and off one at a time:.
This is the pin DIP package. The opinions expressed in those weblogs and hence this aggregation are those of the original authors.
Please subscribe using one of the 74hcc4066 at the top-right of this web page to receive updates on new posts. You press the button, and current can flow through the switch. All these parameters and more are available from the data sheet pdf. Consider the circuit below:.
Well that was interesting. The 74HC switches creates a final voltage through the sum of various currents being switched into the final output.
Today we are going to examine the 74HC quad bilateral switch IC. Sign up for the PlanetArduino Newsletter, which delivers the most popular articles via e-mail to your inbox every week.
And the ubiquitous video: Just fill in the information below and submit. About 74hd4066 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.
It is also available in surface mount, and other newer package styles. And here is the Arduino sketch: Entries on this page are owned by their authors.

My reason for writing this comes from a comment left by a reader on chapter nine of the Arduino tutorial. This was a good suggestion, however the can only switch a current of 10mA per pin. So, what is a quad-bilateral switch? We do not edit, endorse or vouch for the contents of individual posts. Here 74hc066 the schematic: Practice makes perfect and all that. As you can see above, there are four of these switches in the IC.
With regards to the current the IC can switch, Is, the maximum is 25mA per switch. First of all, here is a video of the switches being turned on and off one at a time: Consider the circuit below: For more information about Arduino please visit www.
But when you need a few of them, it can be easier to start using these 74HCs as long as the current requirements are met. Furthermore, this would only apply if the current restrictions of the IC are met. Laid out on the breadboard: 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.
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.
I know these simple demonstrations may be… well a little simple, but after taking the time to build them from scratch you get a better understanding of the part and how they work. Imagine a simple normally-open push button.

Well I hope you found this part review interesting, and helped you think of something new to make. PlanetArduino is powered by WordPress. Our first demonstration is quite simple — just switch on and off some LEDs via a 74HC shift register and an Arduino. As always, thank you for reading and I look forward to your comments and so on. Here is a diagram: Otherwise, have fun, be good to each other — and make something!
Four switches in one IC. Using the 74HC, when current is applied to the E pin, current can pass through from the matching Y pin to the Z pin.
