What do you mean by logic level? 5-volt?  Probably not, since it
would requite the MOSFET to have a whoopy transconductance, and huge
input impedance, and whatever is driving it won't like either.

However, you can use teledyne's logic level driver/level shifter to
drive MOSFET H-bridge.  Rise/fall time is on the order of 30nS into
1000pF.  Scan through a digi-key catalog, you'll find those chips.
