Love this part but have recently had a slight project setback. I was hoping to use this for charlieplexing, as 2 of them would yield control over 240 leds without alot of fancy grid work, but sadly (and not in the datasheet!) each of the 16 lines has a 680ohm pullup resistor on it. Ah well, back to the drawing board :D

Oooo, that looks absolutely delicious.
But… The datasheet seems inconsistent. It shows some other forms of this chip, but doesn’t have this one. It has a similar 28-pin package, but this is 24-pin. Are they similar enough to assume that the pinouts are identical? ( minus four pins? )

Hi,

I need to read/write 16 I2C devices which have the same I2C address (0x68) using only one I2C port in my uC. Is possible to this with this product?

Thank you,

Damn… bought some of these and didn’t notice (until they arrived) that they were not the 28-pin devices in the datasheet but actually a 24-pin package that isn’t mentioned in the datasheet. A few hours of Eagle time down the gurgler :-( I must pay more attention in future.

It comes in a DIP package from TI part number CD74HC4067EE. I understand Sparkfun wishes to push there own products (i.e., SSOP to DIP Adapters) which is great! However I wish Sparkfun would sale this chip it in a DIP package, since it is offered in a DIP package from the manufacture.
Thanks SF.

I’m not sure, but can the PCD8544 LCD Library be used in tandem with this? I’m trying to run 4 LCDs at once, so I need more outputs.
These are the LCDs I’m trying to use: http://www.sparkfun.com/products/10168

There wouldn’t happen to be an eagle part for this, would there?
