Listed By Driver Type
The next table describes the various types of drivers that
are used in the PCnet-PCI II controller:
All IOL and IOH values shown in the table above apply to
5 V signaling. See the section “DC Characteristics” for
the values applying to 3.3 V signaling.
A sustained tri-state signal is a low active signal that is
driven high for one clock period before it is left floating.
