A semiconductor device having conversion units which change the reference potential of an input signal to a first or second reference potential and outputs the input signal to a first drive unit or second drive unit, change the reference potential of a first control signal output from the first drive unit to the second reference potential and outputs the first control signal to the second drive unit, and changes the reference potential of a second control signal output from the second drive unit to the first reference potential and outputs the second control signal to the first drive unit, wherein the conversion units increase currents flowing through the conversion units on the basis of a time when the input signal changes.
