Hi,
I'd like first to thank Pascal for the help he provided, I'm studying the schameatics he suggested and it's the one i needed. The thing is that, while I was analyzing it I've found some things there that i coudn't understand. There are two CIs (74HC244DW and 74LCX244DW) that have their pins 7, respectivally, connected to a box with a number 1 wrote in it. I just can't understand what that means.
If anyone please have sometime to check it out and help me, I'd be thankful.
Regards
