It is usual to allow some tolerance in the voltage levels used; for example, 0 to 2 volts might represent logic 0, and 3 to 5 volts logic 1. A voltage of 2 to 3 volts would be invalid, and occur only in a fault condition or during a logic level transition.

Thanks Swap.

Thanks @Amit.

Thanks @Nisha, @Amit.

The voltage range for the binary signal are:

0 to 0.8 >> Low >> Logic 0 An output voltage 0.8 volts or less is considered to be logic "0".

0.8 to 2 >> invalid Voltages between 0.8 volts and 2.0 volts are considered invalid (illegal).

2 to 3.5 >> High >> Logic 1 When digital logic has an output voltage of two volts or above its output is Considered to be logic "1'.

Thanks @Fatema.
