    Hello all -

    I need a cheap "upgrade" for the ICL7667 MOSFET driver. The peak current is (almost) ok but this device reaches it's max. speed at
    approx. 5 to 10MHz. I need between 20MHz and 30MHz. The package is not so important. The PowerMOSFET threshold is around 4V.
    Unfortunately the common alternatives like TSC426 seem to be a little pricey. Any alternatives? A discrete one? How to control the
    switchover in the outputs?

    regards -
    Henry
