1.8V to 5V Interface or Buffer

Is there an interface buffer that can translate from 1.8V level to 5 V level?

Most 5V buffers that I can find require Vih(min) = 3.5V at Vin=5V.

Could this buffer also drive a FET gate?

Thanks,

Roger

    How much current would this FET gate require?

    Estimate about 1nF input cap, 5V swing and about 100kHz.
    So I would estimate about 1mA.
