Q26 / 100
What is the purpose of a "tri-state buffer" in digital circuits?
Correct! Well done.
Incorrect.
The correct answer is A) A buffer that can output a 0, 1, or a high-impedance ("disconnected") state, allowing multiple devices to share a common bus without conflict
A
Correct Answer
A buffer that can output a 0, 1, or a high-impedance ("disconnected") state, allowing multiple devices to share a common bus without conflict
Explanation
The high-impedance state effectively disconnects the buffer's output from the bus, allowing multiple tri-state buffers to share a common bus line without electrical conflicts, as long as only one drives the line at a time.
