A digital component defines an output voltage between 0 and 0.8V as a logic-0, and an output voltage between 2V and 5V as a logic-1. These voltages are its ___________/?

• A. Logic levels
• B. Thresholds
• C. Drive levels
• D. Compatibility standards

Answer: (A)

Logic levels are the voltage ranges that represent the binary states in a digital circuit. Here, a voltage between 0 and 0.8 V is seen as a logic zero, and a voltage between 2 and 5 V is seen as a logic one. These ranges define the valid output states and provide noise margins, ensuring the signal is read reliably despite small variations. The gap between 0.8 and 2 V is undefined, which helps avoid misreads near the boundary. Thresholds would be the switching points where the device flips between states, not the actual ranges that define the states. Drive levels relate to how much current the output can source or sink, and compatibility standards relate to interchangeability between devices. So these voltages are the logic levels.
