I was thinking more a 22V10 or some other PLD.  The transistor array ... 
wonder if you really need it. The new LEDs are pretty efficient and you 
can get serious brightness with low current. Are the LEDs in question on 
the CS20M individual LEDs or 7-segment or what?  Hopefully the logic 
part doesn't use the 10v!?
