A tri-state digital output can assume logic 0, logic 1, and which additional state?

  • AMetastable only
  • BHigh impedance
  • CNegative resistance
  • DAnalog saturation
Report an error
Correct Answer: B. High impedance
Explanation: When disabled, a tri-state output enters a high-impedance (Hi-Z) state so that it effectively disconnects from a shared bus.
