If the control input is 1 then normal input goes to output (input lines of register in which we have to pass - Register transfer Micro operation ) And if its control input is 0 , then it behave as a open switch , No input is connected to output lines . is this only use of High Impedance State ? 0 votes 0 votes Please log in or register to add a comment.
