Voltage Logic Level (Input/Output)

Information

Logic Level at the input of the Gate is known as Input Logic Level and corresponding voltage range as:

• Logic 1: Start from \(V_{IH}\) (Minimum Input Voltage for Logic High) and Ends at \(V_{DD}\).

• Logic 0: Start from \(V_{SS}\) and Ends at \(V_{IL}\) (Maximum Input Voltage for Logic Low).

Logic Level at the output of the Gate is known as Output Logic Level and corresponding voltage range as:

• Logic 1: Start from \(V_{OH}\) (Minimum Output Voltage for Logic High) and Ends at \(V_{DD}\).

• Logic 0: Start from \(V_{SS}\) and Ends at \(V_{OL}\) (Maximum Output Voltage for Logic Low).

Below Figure, Explains that.
