That would be an ideal single-chip 5 V solution for me but the two parts he mentions, MC1489  and SN55182 , don't appear fast enough for a 10 MHz input.

What about the plethora of LVDS receivers - they're basically a
differential input thresholder, with deliberate hysteresis, looking for
a 300 mV shift across a 100 ohm resistor.
Plenty fast (GHz)
