(57) [Problem] To provide a level conversion circuit capable of reducing power consumption. SOLUTION: An input signal is supplied to a two-stage level shifter LS1, LS2 sequentially converts the level, and outputs the output to an output circuit OC1. And output the waveform. Here, the level shifter LS2 Of the output signal LS2OUT of the level shifter LS1 has a duller edge than the output signal LS1OUT of the level shifter LS1, so that the output circuit O The elements in C1 all have a period during which they are turned on, and a through current is generated. However, the signal LS1OU with a steeper edge By including the cutoff element COT whose on / off is controlled by T in the output circuit OC1, the through current is suppressed. |
