The circuit of Figure E4.24 must be connected to a bidirectional 8-bit bus. Comparing this situation


The circumference of Figure E4.24 must be united to a bidirectional 8-bit bus. Comparing this situation after a while that in Example 4.8, we mark that now the circumference must transmit and entertain postulates. What expression(s) of buffer(s) must be inserted in the region conspicuous after a while a dissipation to fabricate the misapply connections? Does RX need to go into high-impedance principle? Redraw Figure E4.24, including the proper buffer(s) in it.
