A driving circuit is provided by the invention. The driving circuit includes a level shifter, a buffer and a switch. The switch is coupled between an operation voltage and a power supply terminal of the first buffer for controlling a power-supplying time of the first buffer. While the level shifter is transiting, the switch is turned off, and the switch is turned on after the level shifter completes the transition. Therefore, the transition time of the level shifter is different from the transition time of the buffer so as to avoid simultaneously conducting large currents to adversely affect the transition capability of the level shifter.
