Is possible to this with this product?</p><p>Thank you,</p></p>

A few hours of Eagle time down the gurgler :-( I must pay more attention in future.</p>

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</p>

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.<br>
Thanks SF.</p>

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? )</p>

These are the LCDs I'm trying to use: http://www.sparkfun.com/products/10168</p>
