Listed By Driver Type

The following table describes the various types of out-

put drivers used in the Am79C971 controller. All IOL and

IOH values shown in the table apply to 5 V signaling.

See the DC Characteristics section for the values ap-

plying 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.

DO, TDO, and TPO are differential output drivers. Their

characteristics and the one of the XTAL output are de-

scribed in the DC Characteristics section.
