Internal Line Status
Internal Line Status
= Propagation delay for the low-high line status change
= Voltage region considered to indicate a "high" internal logical level
= Voltage region considered to indicate a "low" internal logical level
= Transition threshold
= Propagation delay for the high-low line status change
