What "signal"?
What is the current you need?

any signal, I just need to change 5V to 60V.

Really, I don't know :oops:
This is a loaded question... 'Any Signal' is hard to do unless you attempt to build an amplifier that can amplify DC or AC.
What are you connecting it to?

If it's just a simple on|off signal, you can use a relay or transistor to provide the 60V to what you need... if not it gets more complicated.

o.k.
So you wont to have the same 0-5V signal at a larger amplitude 0-60V. and you already have a 60V DC voltage.
That is called "level translation"
You do need to know what is the load and the frequency/rise/fall time of the 60V signal and current..
a simple general solution :

250hz frequency.

i did smth like this, but it reverse the signals
Yes, because the transistor you used is a PNP, which requires a 'Low' signal on the base to turn on.
You need to invert your signal before-hand, or you can use an NPN transistor and a resistor instead *but* we don't know the current draw, so your safest bet is to re-program your IC to provide an inverted signal, or put an inverter in series with the transistor.

No!
This will not work since the PNP will always be on with both
outputs of the IC(0 or 5v).

Use an NPN with inversion of the signal by the IC(if possible) like @Gryd3 suggested .

Edit: A base resistor is needed in both NPN and PNP cases.
and you need to calculate both resistors.

I really can't understand what you are saying, may you draw smth to explain more

Put a resistor between ground and the transistor.
Put Channel 'D' between the Resistor and Transistor.

Is there any integrated circuit can do that for me ? (without the resistors, the transistors ...). coz i have more than one signal, and it kinda gonna be more complicated

hrm... Maybe? I would expect it to require more parts than a pair of resistors and a transistor though...
We still don't have all the details from you.

Why a 60V signal? What is the current draw requriement?

I have to command a Chopper (to value a motor speed), and it works with 60V
Do you have any specs? Rise-Time and Fall-Time as well as current are very important... or you will have to do trial and error to see what works, and you can expect a couple parts to pop if they are chosen incorrectly.
