Hi, I have been looking around for a nice solution to driving 3no. large 7 LED segment displays @ 12V and came across this thread: http://www.arduino.cc/cgi-bin/yabb2/YaBB.pl?num=1212882269/15 - the last post in the thread is very neat so happy to have found a good solution I headed out to find some Allegro 6278EAT chips for the project..... only to find they are out of production????? ??? ????????? ????? ?????????? ????????? ????? ????? ????? ????? ??? ????? ?????????? ???????? ???????? automasys.wordpress.com ????? ?????????????? ???????? ???? ????? ??????

I'm wondering if anyone can suggest an alterntive chip or an equally nice solution to the problem....
I suggest using ULN or UDN drivers or for better performance MBI LED driver series.
