Mechanical and Electrical Specifications
5.9 AC electrical characteristics
Tests are conducted using the input levels specified in Table 5. Unless otherwise
specified, propagation delays are measured from one 50% point to the next 50% point,
and rise and fall times are measured between the 10% and 90% points, as shown in
Figure 8.
Figure 8. Input signal measurement references
Figure 9 shows the definitions of the following signal states:
• Data Active state, when a bus or signal is driven, and enters a low impedance
state
• Data Tri-stated, when a bus or signal is placed in a high impedance state
• Data Valid state, when a signal level has reached V_OL or V_OH
• Data Invalid state, when a signal level is in transition between V_OL and V_OH
