Yes. Resistors for that purpose, and to limit
dv/dt during switching, are indicated in the typical connection diagram at the bottom of the first page of the IR2104 datasheet, linked in my
earlier post.

I believe in intuition and inspiration. Imagination is more important than knowledge. For knowledge is limited, whereas imagination embraces the entire world, stimulating progress, giving birth to evolution. It is, strictly speaking, a real factor in scientific research.
