Ok I know how to use a transistor to turn a device on and off. Could some one show me how you do the same but with using a mosfet. I wish to use ttl level logic to turn on a mosfet. Thanks

S.O.S (same old s**t). Your controling driver sends signal to a device which changes its resistance. So look at the data sheets and adjust the drive accordingly.

What load?
Most small signal /switching MOSFETS will operate with TTL levels (and LVTTL levels), but much depend on the load (of course, it's easy to control a larger switch with a small one).
However, you say you know how to use a transistor (one must assume a bipolar) to turn a device on and off. The principle using a FET is much the same. I recommend some data sheet reading. (Try the 2N7002 for a start)

A couple weeks ago, I bought some mosfets - never used them much before. I found a use for one running my Dremel tool....

Now I see why they are so popular!

** Groper Alert !!!!!!!!!!
** No problemo.....
Just use a "logic level " mosfet.
The catalogues are full of them.
