Driving 220/330 terminated loads

[Steve Thatcher]

the only time a totem-pole output would have an issue if it had to fight another output - one low and one high. As long as you are driving using a single output that has to deal with the resistor network, you should be just fine. The interface you are describing is basically the same as on a 8" disk drive.
