Does anyone know the Output current on High and Low for the output pins?
I find some in the data sheet,but I’m not sure, if they are right.

Is there some reason you doubt the Atf16v8 and atf22v10 data sheets? Just curious.

As for your display, I gather you'll have two 7-segment digits of the common Cathode type. So, there are two signals -- those which drive the common cathodes -- which must supply the high current. This can be accomplished by using some sort of buffer between the CPLD and the common cathodes.

A couple of discrete transistors -- one for each signal -- would do the trick.

I have to use a single FET Switch.

Alternatively, there are various ICs which could do the job. Example: A 74AC240 or '244. On each half, you'd connect the four inputs together and the four outputs together in order to quadruple the current capability.

Meawhile i have done this without any other parts involved. Simply a ATF22V10C, 2 common anode 7-segmant displays, and 7 150Ohm resistors. works, the chip even get warm.

For me it's not clear, if the term:
IOS(1) Output Short Circuit Current VOUT = 0.5 V -130 mA
is the term per Output pin

I haven't looked at the ATF22V10C specs, but the outputs are probably quite a lot stronger when pulling low than when pulling high. That suggests that you'd do "better" using common cathode displays. (I'm assuming you only use the parts you have on hand, and aren't willing to add a FET, a BJT or an IC to act as a buffer.)

But you've already gotten the project working, so maybe "better" doesn't matter! Common cathode displays will probably allow you to achieve the same brightness with higher resistor values (thus allowing the CPLD to run cooler), but....

The footnote (1) explains that short circuit current is only allowed for 1 pin at a time, and only for 30 seconds.

So, with the actual design i have max -80mA on average on the output col pins and 20mA on the other. (with all segments on) The chip is getting warm but not hot.
