Abstract
A device is disclosed herein, which may be used a level-shift circuit. The device includes first, second and third power supply lines supplied respectively with first, second and third power voltages that are different from one another, first and second input terminals and an output terminal, an output circuit coupled to the first power supply line, the first and second input terminals and the output terminal, a first inverter including an input node coupled to the first input terminal and an output node coupled to the second input terminal, a first transistor coupled in series to the first inverter between the second and third power supply lines, the first transistor being rendered non-conductive to deactivate the first inverter, and a control circuit configured to prevent the output terminal from being brought into an electrical floating state during deactivation of the first inverter.
