Buffer is a Logic gate, whose output is the same as the input. It has a high current driving capability. It is typically used in digital circuits when one wants to drive the low impedance load or to increase the circuit's fanout. What is Tri-State Buffer? It is the buffer with two inputs. The Data Input and Control Input. The control input decides whether the input will reach to the output or not. When the control input is high then the Tri-State buffer acts as a normal buffer. And when the control input is low then it operates in Hi-Z mode. In this mode, the buffer provides high impedance and it isolates the output from the input side. This buffer has three output states, logic '1', logic '0', and Hi-Z mode. Since it has three output states, so it is known as the Tri-State Buffer or Three State Buffer. This video will be helpful to all the students of science and engineering in understanding what is buffer and Tri-State buffer, and why they are used in digital circuits. #allaboutelectronicsquiz #digitalelectronics #logicgates Support the channel through a membership program:    / @allaboutelectronics   -------------------------------------------------------------------------------------------------- Follow my second channel:    / @allaboutelectronics-quiz   Follow me on Facebook:   / allaboutelecronics   Follow me on Instagram:   / all_about.electronics   -------------------------------------------------------------------------------------------------- Music Credit: http://www.bensound.com
