10.3 AC Electrical Characteristics
Tests are conducted using the input levels specified in
propagation delays are measured from the 50% to the 50% point, and rise and fall times are measured
between the 10% and 90% points, as shown in

Input Signal
Note: The midpoint is V
Active state, when a bus or signal is driven, and enters a low impedance state
Tri-stated, when a bus or signal is placed in a high impedance state
Data Valid state, when a signal level has reached V
Data Invalid state, when a signal level is in transition between V
shows the definitions of the following signal states:
