What is the typical invalid voltage for a binary signal ?
Answer: C
The typical invalid range is 0.8-2 volts.
For standard TTL logic, an input of 0.8 V or less is read as logic 0, and an input of 2.0 V or more as logic 1. Voltages between 0.8 V and 2.0 V are neither a valid 0 nor a valid 1, so they form the invalid (indeterminate) region.
The other ranges do not match these TTL thresholds.
Logic families define such a forbidden band so that noise on a signal near one level is not mistaken for the other level; inputs are expected to cross it quickly.
