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
Data Invalid State
