For example, if I'm using a Force Sensitive Resistor (like this https://www.sparkfun.com/products/9375), can I get a value from 0-1023? I initially started using a different chip (the MCP23017), but quickly learned that, while it says it is for analog and digital inputs/outputs, it can only return digital readings -- so I'm only getting a 0 or 1 from the Force Sensitive Resistor.</p>

I only ask because I've checked out the MUX Breakout II but I haven't dissected it yet but it looks like they have incorporated 6 shift registers, wouldn't it just be easier, smaller, cheaper and more powerful to just use another CD74HC4067 to talk to up to 16 other CD74HC4067s?</p>

is there anyway to use C0-C7 as analog inputs & C8-C15 as digital outputs at the same time?
basically im wanting to read 8 pots in sequence and light an indicator LED so you know which pot is active.
would be great if i can utilize those extra 8 pins on this board instead of having to use a shift register chip for the leds :)<p>Thanks..</p></p>

When using this chip to read multiple sensors (switches) I have been pulling each of the 16 inputs low with a resistor (one for each pin) which is a total mess, especially when piggybacking this on a protoshield (leaves no space for... anything else.) and then something donned on me: Can I just use 1 resistor to pull the SIG pin low and let the switches float?

I can't get it to switch inputs. No matter what, I just get the input from C0. EN is set to low, and I'm pretty sure it's all wired right. Is there a need for a delay or something between switching inputs and reading that input? Does EN ever need to be set high?<br>
I'm trying to wire this thing pretty simply to an Arduino. Are there any sample schematics or code to show how to use this?</p>

Do the output pins have memory of what they were set to? The datasheet is kind of lacking in that info, maybe it's [un]common knowledge what I'm asking?<br>
I'm trying to attach many simple on-off devices to an MCU but I'd like to know if I have to put in an output buffer or flip-flop or something.</p>

The S0-S3 act as an address so if you're measuring multiple inputs coming from the C0-C15 side you set S0-S3 to that binary pin # and read it on the SIG pin. I had assumed that a 1 on say C8 would generate a 1000 on the S lines. In this instance you have to set S to 1000 and then the value reads in on SIG.<br>
Just for anyones info if they were having problems like I was. I didn't quite understand that from the data sheet.</p>

I spent a good few hours debugging what I thought was a flaw in my looping algorithm when it turned out that two of the legs on the MUX chip were just barely soldered together causing one of the digital pins always to return a 0. All it took was a little bit of scraping with an exacto knife, but it took hours to track down.</p>

This is used to connect 16 analogue sources to one A/D pin. Besides, servos need constant attention with their signal to work properly. You can use something like the Serial Servo Controller or convert some servos with the OpenServo boards and control them all with two lines with I2C.</p>

Bandwidth will be limited by the output load's capacitance. Might work for video with short cable length. It doesn't look like they sized the traces for 50 or 75 ohm impedance, but the trace lengths on this tiny board are very short so that shouldn't be an issue.</p>

Use page 2 of the data sheet to see how to select pins.</p>

Do you guys have any idea how much of the last two weeks I spent hand-soldering these CD74HC4067 ICs to your 28-SSOP boards with a 15w P.O.S. RadioShack iron? Clearly not, or you'd be begging to make it up to me. Is there a reason you didn't mention your intention to break these out? It's a spectacular product, but that really is too cruel. =P<br>
I can't recommend this multiplexer highly enough. Love you guys ;-) Keep up the good work!</p>
