Driving 220/330 terminated loads

I know the "right" answer to this one--you drive 220/330 ohm 
terminated loads with 7438-type OC drivers.  But, going a bit afield 
from "correct", can one drive a single 220/330 ohm terminated load at 
the end of a 3m length of ribbon cable at 1 MHz using plain old totem-
pole STTL output?  How about an LSTTL or HCT totem-pole driver? 

You can assume that the receiver is a 74LS14.

Thanks,
Chuck
