Which voltage range is typically associated with the "on" state of a logic gate?

The voltage range typically associated with the "on" state of a logic gate is generally found within the 3.5 to 5 volts range. In digital electronics, logic gates are designed to recognize specific voltage levels as representing logical high (or "1") and logical low (or "0").

For most standard TTL (Transistor-Transistor Logic) and CMOS (Complementary Metal-Oxide-Semiconductor) logic families, the "high" state often corresponds to voltages close to the supply voltage used for the gate. For TTL devices, this is usually around 5 volts, while CMOS devices can operate at various voltages but often work efficiently within the 3.5 to 5-volt range, ensuring reliable logic level recognition.

The other voltage ranges do not typically signify the "on" state for standard logic gates. The ranges of 0 to 1 volts and 1 to 2 volts are typically considered "off" states or undefined regions, while 5 to 10 volts exceeds the common operational voltages for most logic families. In applications involving logic gates, utilizing the appropriate voltage level significantly affects the performance and reliability of digital circuits.
