A while ago, I told all of you about a 16 channel led driver by TI. This one is supposedly a little harder getting hold of.

I don't care where you get it but you can find a little more about it here:

Have fun.

Man, they are cool!

I will certainly be thinking about using them as an alternative for the LEDBOY project. it basically combines three chips I was using into one!

The Arduino crowd will be buying them up for their Centipede shield (daughterboard) which adds 64 I/O pins. It appears from the daughterboard picture that each board uses four chips. Therefore it might be wise to check availability.

If there is a shortage, I know that Mouser gives delivery dates so you can be the early bird that gets the worm.

Well, I'm going to have to practice my binary numbers to use these things.
