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.

I was thinking of driving the lines with an LS540.
which has an I(OL)
of 24 ma per output. What I was curious about was if the low-level
sink current is sufficient, will I run into problems with the totem-
pole pullup? In other words, do I really need OC drivers?
Thanks,
Chuck
