The 74HC switches creates a final voltage through the sum of various currents being switched into the final output. All these parameters and more are available from the data sheet pdf.
And the ubiquitous video: First of all, here is a video of the switches being turned on and off one at a time: Well I hope 74hcc4066 found this part review interesting, and helped you think of something new to make. First of all, here is a video of the switches being turned on and off one at a time:.
PlanetArduino is powered by WordPress. The opinions expressed in those weblogs and hence this aggregation are those of the original authors. Consider the circuit below: Just fill in the information below and submit.
As always, thank you for reading and I look forward to your comments and so on. Furthermore, this would only apply if the current restrictions of the IC are met. Our first demonstration is quite simple — just switch on and off some LEDs via a 74HC shift register and an 74h4066.
This was a good suggestion, however the can only switch a current 74hhc4066 10mA per pin. Today we are going to examine the 74HC quad bilateral switch IC.
This is the pin DIP package. Sign up for the PlanetArduino Newsletter, which delivers the most popular articles via e-mail to your inbox every week.
Here is the schematic: Imagine a simple normally-open push button. Four switches in one IC. 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. You press the button, and current can flow through the switch. Consider the circuit below:. About 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.
Laid out on the breadboard: My reason for writing this comes from a comment left by a reader on chapter nine of the Arduino tutorial. 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.
So, what is a quad-bilateral switch? It is also available in surface mount, and other newer package styles. And here is the Arduino sketch: Please subscribe using one of the methods at the top-right of this web page to receive updates on new posts. As you can see above, there are four of these switches in the IC.
Well that was interesting. With regards to the current the IC can switch, Is, the maximum is 25mA per switch. Here is a diagram: 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. Otherwise, have fun, be good to each other — and make something! Practice makes perfect and all that. Using the 74HC, when current is applied 74hc466 the E pin, current can pass through from the matching Y pin to the Z pin.
