PROBLEM TO BE SOLVED: To reduce current consumption by the transfer of small amplitude data by attaining differential transmission without increasing the number of wires. SOLUTION: In the first half of one period of a main clock, one multiplexer 13 selects a signal Ain and the other multiplexer 14 selects an inverted signal, the inverse of Ain. Thereby the signal Ain is sent to a signal line 1 allocated to the signal Ain, the signal, the inverse of Ain, is sent to a signal line 2 allocated to a signal Bin and the differential transmission of the signal Ain is executed. In the latter half of one period of the main clock, the multiplexer 13 selects an inverted signal, the inverse of Bin, and the multiplexer 14 selects the signal Bin. Thereby the inverted signal, the inverse of Bin, is sent to the signal line 1 allocated to the signal Ain, the signal Bin is sent to the signal line 2 allocated to the signal Bin and the differential transmission of the signal Bin is executed. |
