Question 1: Explain Tri-State Buffers with the help of block diagram
Answer:
Tri-State Buffer is a NOT gate with a control line that disconnects the output from the input. When the control line is high the buffer operates like a NOT gate and when the control line is low the output is disconnected from the output and high impedance is seen at the output. Tri-state buffers are used to disconnect the outputs of devices which are connected or share a common output line. (Page 196)
