I see that some "logic buffers" are often used between the MCU and the motor driver chip. What are the functions of these buffers?

Usually it increases the output current, and some can also increase the output voltage.

Will it have an isolating effect?

That depends on how you define "isolation".

Usually, "isolation" means that there is no electrical connection between two parts. If this is the definition, the so-called "buffer" does not have an "isolation" effect.
