What is tri-state logic?
Pick an answer to check it.
Answer: A. Logic devices with 0, 1, and high-impedance output states
Tri-state logic outputs can be 0, 1, or a high-impedance off state. High impedance lets many devices share the same bus without interfering.
Tip: Tri-state: high, low, or disconnected.
