I'm considering using TWO 574s. Load all 216 574s and then all at once clock in the pixels for a row. This would allow the most on time. Is it worth the extra $60 in 574s? One benefit is that it would allow for a MUCH slower clock rate to the registers. I could take up to 10-14ms without any trouble.
In which case it's NOT a 2N2222 !
Show me 2N2222s for 1 cent please.
Of course its true. Less Ib loading of a bias network for example.
That is a truly absurd comment.
What on earth do you think is going to happen here ?
Overdesign won't win you any friends when the kit gets costed.

I can't say I find the thinking behind that very compelling. It would seem perhaps to be about the only thing going for the part though.

I could afford the expensive part because I did save a ton on the LEDs. :) Got them all new old stock for .6 cents a piece.
Any ideas on the register situation?
Sure it is; I\'m still me no matter what I\'m wearing.
Now you\'re just being pig-headed.
There\'s absolutely nothing wrong with 2N2222\'s or their differently
garbed counterparts when they\'re used properly. As a matter of
fact, they\'ve got a lot going for them when you look at their cost.
