Stage: PROBLEM TO BE SOLVED: To provide a signal transmitter with which it is possible to speed up switching between in-phase transmission and differential transmission.SOLUTION: A transmission buffer of the signal transmitter according to an embodiment includes a differential circuit unit that is connected between a first potential and a second potential, a variable current source unit that supplies a current to the differential circuit unit, a switch unit that switches states from a conductive state to a cutoff state and vice versa between a first transmission terminal and a fixed potential and between a second transmission terminal and the fixed potential, and a control unit that controls the current supplied to the differential circuit unit by the variable current source unit and controls the switch unit. A reception buffer includes a first differential pair of first conductive type that is connected between a third potential and a fourth potential, a second differential pair of second conductive type that is connected between the third potential and the fourth potential and outputs a third reception current in accordance with a first transmission signal, and outputs a fourth reception current in accordance with a second transmission signal, a first current mirror unit, and a second current mirror unit.SELECTED DRAWING: Figure 1 (Grant)
