  • Publication number: 20230006660
    Abstract: A level shifter can achieve a level shift by a wide margin. The level shifter includes a latch circuit, a clamping circuit, a protection circuit, and an input circuit. The latch circuit is coupled between a high-voltage terminal and a pair of output terminals for outputting a pair of output signals. The clamping circuit is coupled between a medium-voltage terminal and the pair of output terminals and limits the minimum voltage of the pair of output signals to the medium voltage. The protection circuit is set between the latch circuit and the input circuit, and prevents an excessive voltage drop between the input circuit and the pair of output terminals. The input circuit includes an input transistor pair coupled between the protection circuit and a low-voltage terminal having a low voltage. The input transistor pair receives a pair of input signals and operates accordingly.
