Test apparatus and driver circuit

A driver circuit that generates an output signal corresponding to an input pattern, comprising:

• an input gate drive section that selects one of a plurality of input drive voltages supplied thereto, according to a logic value of the input pattern, and outputs the selected input drive voltage;
• a voltage switching section that includes a transistor and that outputs the output signal according to the drain voltage of the transistor, the transistor having a gate terminal that receives the input drive voltage output by the input gate drive section and a source terminal to which is applied a prescribed reference voltage;
• and
• an input drive voltage supplying section that generates the input drive voltages according to the reference voltage, and supplies the input drive voltages to the input gate drive section.
