How To Amplify a Signal?

Hey

For this circuit I was wondering if it is ok to use this circuit multiple times all coming from the same microcontroller pin?

This would meanh nmos gates would all be at 3.3V and circuit would operate as normal but obviously current will change. How will this affect the circuit?

Cheers
 

It will be fine. With an NMOS there will be no DC load on the microcontroller pin. The only effect will be to slow down the turn on/off times.
