Hello Does someone know how to wire up a DM74LS47N? ( DM74LS47N Datasheet(PDF) - Fairchild Semiconductor ) The outputs for the segments are obvious but I do not understand the inputs. I need to hook up 4 of them. Thank you! Fubbi

How can I chain 4 of them? or do i need all those outputs for each chip?

thanks

fubbi
