PURPOSE:To realize transmission of long distance at medium speed by sending the current of positive and negative power sources to a load side by distributing to a signal line alternately corresponding to the levels [0] and [1] of a driving signal. CONSTITUTION:The title device is constituted in such a way that the positive and negative power sources EIa and EIb are arranged, and a negative current flows from a transistor TR5 when the driving signal S is set at [0], and a positive current flows from a transistor TR4 when it is set at [1] to the signal line L. In other words, since a system is set at the one of bidirectional current sending system by the positive and negative currents, it is possible to absorb a load due to capacity between the signal lines generated when the positive current flows when the negative current flows. In such a way, the driving signal S can be accurately transmitted even on a long distance line. |
