Abstract
The invention relates to a bidirectional communication line buffer apparatus in which the communication direction of data of a bidirectional data line and the length of the data are judged. A bidirectional buffer circuit receives the results of such judgement and is made non-conductive on the basis of a data termination indication obtained from the received judgement after data is conducted in the communication direction based on the received judgement. Accordingly, the communication data waveform shaping and the driving capability are improved.
