The details are in the data sheet. It depends upon which IO standard you are using.

I haven't seen the term "fanout" in data sheets for a long time. It doesn't really make much sense with modern logic.

CMOS has almost 0 load current so you can drive hundreds of loads if you don't care about speed. The data sheet will give you the switching times for a specified load capacitance. If you have more capacitance it takes longer.

Though, you have to care for input rise and fall time requirements of the attached receivers.
