摘要:
A bidirectional buffer having a high impedance state is provided. This buffer is used for amplifying a signal as it is passed from one transmission line to another when it is desirable to select which direction the signal will flow. A switching circuit controls which transmission line is connected to the input terminal of the buffer and which is connected to the output terminal. A high impedance state is also provided for disconnecting the two transmission lines. Two memory cells control the direction of signal flow and the high impedance state.
