Check out RS 198-4195, Philips PHN210 dual logic level MOSFET in SO-8
package. I selected this on the basis of cheap price when looking for such a
device, but have not yet got around to using it. Another trick with this
package is that many manufacturers make devices with the same pinout, so you
are not single source tied if things go belly up with a manufacturer.
