I am trying to build my own H-Brigde (for fun and practice) DC motor driver, and I was supposed to get a FQP30N06L, which is logic level. But the shop didn't have any, so I asked for something similar, most important feature being the logic level.

So I got the mentioned IRF840 and IRF4905, but after googeling and reading a bit, I find that they are not. For future references, how to do tell if it is logic level or not?

Can I work around this, say use a NPN/PNP for level shifting?

I don't have any drawing yet, as I haven't quite started, but it's just a simple tiny 12V DC motor that I am trying to control.
