Design project 2: MC74AC245 is an octal bidirectional transceiver with 3-state inputs/outputs. One pair of it can be shown by the symbol in Fig. 1. DM74LS153 is a dual 1-of-4 line data selectors/multiplexers. The symbol for 4-to-1 is shown in Fig.2. Fig. 1 Fig.2
Design the following 3-state 2 * 2 switch by using the bidirectional transceiver, multiplexor, and other gates. Assume the signal line is one bit. Fig. 3
