HCF4066BE ?

Does anyone know what a HCF4066BE is and how do i use it? Heres a link http://www.aliexpress.com/store/product/HCF4066BE/426260_1102648480.html
i did find some datasheets about this item but i still dont really understand what this is and where i could use it.
I am asking because i found a few of them salvaging parts. Thanks for helping in any way possible

It's a Quad Bilateral Switch, like four switches that are each controlled by a logic input. They are useful for steering analog signals.

But not so useful for switching digital lines or anything requiring a low resistance (less than 100 Ohms) switch where if you are using 5V logic as you would with Arduinox, you use a 74HC4066 instead.

any documentation in the arduino playground on how to use em or any projects done with them?(Im also gonna check myself)

It is best if you check it out for yourself first.

Did you read the datasheet ? That's where anyone would look for information on how to use them , right ?
(that is the purpose of a datasheet is it not ?)
What is the problem ?

You need to have an application to decide how to use it. (single supply, bi-polar , etc).
Do you have an application ?

I used four of them in this project

Excellent example of an application for that chip.

Very clever!

Mind you, it is probably simpler to use an ATmega328 and a couple of 74HC4051s.

Or actually, just an ATmega328.

No doubt, but this was designed and published in 1996 for a computer with only an 8 bit printer port and an I2C bus, so it was designed to fit those constraints.

thanks for the great example :slight_smile:
