Some FETS ok at low voltage. | |

Depending on how much drive you need, that would determine what sequence I'd put the chips. Afterall, the 7414 is only inverting and squaring up the signal logic so it can be rather forgiving where it is placed. I"d be inclined to have the 7414 properly trigger an adequate driver as opposed to driving a transistor directly, espcially if you're looking for speed.
Driving a fet with only 5v will not switch it on fast or hard enough. Will it work? Yes. Will it work better/cooler with a proper driver? Yes. |
Ther are some MOSFETS that only need 5v on the gate.
