If you now the thresholds, L's and W's you can calculate the output voltage.Any voltage between VIL and VIH is no mans land. A voltage in that range will result in an unpredictable output. This may happen with a disabled tri-state output when it is in the high impedance state.
wow, thank you very much for explaining it to me.VOH is the minimum output high voltage of the inverter.
VOL is the maximum output low voltage of the inverter.
When you connect the output of the inverter to another logic circuit, you must insure that the following inequalities hold:
As you might suspect VIH is the minimum Input High voltage of a logic gate, and VIL is the maximum input low voltage. Here is the really important point: Any voltage between VIL and VIH is no mans land. A voltage in that range will result in an unpredictable output. This may happen with a disabled tri-state output when it is in the high impedance state.
- VOH > VIH
- VOL < VIL
