Hi there,
I am doing a project using arduino mega.In this project i have to take 64 outputs from arduino mega (5V) and i have to do some combinations in loop with all these 64 outputs(like 10110110...).The problem is that i need an output of at least 60V to run the board.My question is : how i can build a circuit between arduino and the board to take all the 64 arduino outputs(5V) to atleast 60V?
I don't understand fully, but seems there are some transistors in your future.
Do you mean there are 60V inputs to some other board and the Arduino's 5V must control them?
You could do that with an open collector transistor, like in an optocoupler. The 5V at top right of the pic could be your 60V, if you pick an opto that handles 60V.

Thank you
So presumably I understood your question?
If you do it according to that diagram, then the 60V on the right will be switched by the digital signal on the left.
Don't quote me but I think the 4N25 can handle 70V but you should check. And it doesn't have to be an opto, can be a "normal" transistor.
Also I'm no expert on this, so before you attach 60V to something you should perhaps await a few more replies.

You haven't provided enough information.
Say what you need to drive, "the board" and "atleast 60V" are not part numbers and specifications.
60V and 1mA? 60V and 100A? 60V into a capacitive load? 60V into an inductive load? All these
details are crucial.
