So, what is a quad-bilateral switch? Four switches in one IC. Please subscribe using one of the methods at the top-right of this web page to receive updates on new posts.
Using the 74HC, when current is applied to the E pin, current can pass through from the matching Y pin to the Z pin.
As always, thank you for reading and I look forward to your comments and so on. This is the pin DIP package.
PlanetArduino is powered by WordPress. First of all, here is a video of the switches being turned on and off one at a time:. And here is the Arduino sketch: Practice makes perfect and all that. First of all, here is a video of the switches being turned on and off one at a time: As you can see above, there are four of these switches in the IC.

774hc4066 For more information about Arduino please visit www. Otherwise, have fun, be good to each other — and make something! Just fill in the information below and submit. This was a good suggestion, however the can only switch a current of 10mA per pin. 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. Here is a diagram: Entries on this page are owned by their authors.
74hc0466 Consider the circuit below:. 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: 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.
The opinions expressed in those weblogs and hence this aggregation are those of the original authors. Well that was interesting. With regards to the current 74hcc4066 IC can switch, Is, the maximum is 25mA per switch.
Consider the circuit below: Furthermore, this would only apply if the current restrictions of the IC are met. The 74HC switches creates a final voltage through the sum of various currents being switched into the final 74h4c066. And the ubiquitous video: My reason for writing this comes from a comment left by a reader on chapter nine of the Arduino tutorial.
All these parameters and more are available from the data sheet pdf. 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.

Our first demonstration is 74hx4066 simple — just switch on and off some LEDs via a 74HC shift register and an Arduino. Imagine a simple normally-open push button.
Today we are going to examine the 74HC quad bilateral switch IC. It is also available in surface mount, and other newer package styles. 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.
Here is the schematic: Well I hope you found this part review interesting, and helped you think of something new to make.
