THVD2410: logic drive strength?

Placing a CMOS driver directly into multiple CMOS inputs is okay. It's ultimately a RC constant where the C increases as you increase the inputs. The R is the Routput's Ron for VOH/VOL. Ron should be strong enough to drive 10 inputs though your max data rate may start to get limited if you add too many inputs (10 inputs is probably fine unless you do something weird like add more cap or series resistance.)

You shouldn't connect CMOS outputs together. You can run into contention when one logic outputs high and another outputs low. This can cause damage over time and look like a short circuit which can cause the power supply to collapse if it's not rated for the supply current. 

You would need to ensure only one Routput is active or set up some kind of open drain circuit to prevent contention from occurring. 

The reference design looks like it mitigates this issue by using digital logic (AND gates?)....
