Multiple output MOSFET array driver

[[email protected]]

Does anyone know of a mosfet driver which can handle more than 4
separate outputs? I am trying to drive 16 lamps (14VDC) from a
microcontroller and would prefer to have something more manageable than
16 IRF-510 mosfets. Maybe a 8 or 16 output device?

Thanks,

Those IRF510 mosfets are marginal when driven with (5 volt) micros.
How about a couple ULN2003 darlington arrays -- good for about 1 amp if
you don't need them all at once?

If you can live with a ground connected switch, there are good low level
SOT23 Mosfets out there that could do the task.
